    ホログラフィックメモリの記録密度を大きく改善すると期待される複素振幅信号光を生成する方法を解説する。記録ページの高解像度化は,1枚当たりの情報量の改善には有効であるものの,記録に必要な露光面積が大きくなるため,実質的な情報記録密度を改善することができない。一方,振幅および位相によりシンボルを多値化する方法が,露光面積を変えることなく情報量を大きくすることができ,ホログラフィックメモリの記録密度を高めるために有用である。その原理を説明するとともに,簡易な光学系で複素振幅信号を生成する位相交互配置法を紹介する。

    ホログラフィックメモリにSQAM信号を記録する二重露光法を提案している.二つの位相変調信号に対するホログラムを同一領域に多重記録することによって,等価的に複素振幅信号のホログラムを生成できる.同手法は,一つの空間変調器を使用した小型な光学系でSQAM信号を記録できるという利点がある一方で,多重ホログラム間に強度差や位相差が生じると,さらにピクセル間干渉が生じると,著しく再生精度が劣化する問題を有する.本報告では,パイロット信号を用いてホログラム間の強度差,位相差による信号劣化の補正,ターボ符号による誤り訂正,FIRフィルタ設計によるピクセル間干渉の抑制を組み合わせて,出力SQAM信号の再生精度を大きく改善する手法を提案した.三つの手法を効果的に組み合わせて使用することにより,エラーレートを大きく改善できることを示した.

    次世代の大容量光メモリとしてホログラフィックメモリの開発が期待されている.記憶容量を改善する方法として,従来の2値の強度ページデータに代わり,近年,多値の複素振幅信号を記録する手法が検討されている.ただし,再生信号の位相分布を計測するためには,光干渉計が必要となり,光学系の複雑化が問題となる.本報告では,線形位相が付加された複数の強度ページを多重した複素振幅信号を記録する手法を提案している.再生時に,復号キーに対応する線形位相を付加し,適切な空間フィルタを通過させることで,元の強度ページデータを個別に抽出できることを示した.同方式では,複素振幅信号としてホログラフィックメモリに記録され,再生時は強度分布として計測できる.使用するレンズの焦点距離,1枚のSQAM信号ページに多重する強度ページの枚数に対する再生信号のSNRの関係を数値解析により評価した.

    The wavelength division multiplexing (WDM) technology effectively increases the bandwidth capacity of a communication line without installing additional fibers and increasing data bit rate to high levels. Optical add-drop modules are key components in WDM optical networks.
    We propose two types of all-optical tunable filter with a photorefractive planar waveguide. The photo-induced index grating in the PR waveguide by control beams drops off a part of wavelength components in the WDM signal beam. It make possible to select the wavelength components of the signal beam by optically adjusting the wave vector of the grating. It is also possible to control bandwidth of the output signal by adjusting the broadening of the grating in the waveguide. The photorefractive effect is known as one of the most efficient nonlinear effects, and therefore the device is controllable by the relative low beam power comparing with the conventional devices using non-linear optical effects.
    The channel crosstalk is generated by using uniformly broadened index grating. We note that the nonreciprocal energy transfer between the two control beams via a photorefractive two-wave mixing causes the nonuniform index grating like Gaussian profile. We therefore suggest the suppression method of channel crosstalk by adjusting the incident intensity of the control beams.

    In this paper, we propose all-optical multifunctional logic gates for image information using photorefractive (PR) two-wave mixing. The optical setup is simply configured compared with the other all-optical logic gates for image information. The XOR-, OR-, and AND-operation are all-optically performed in the same optical setup through the transitional response of the PR medium. One can switch these logic operations simply by means of the on-off control of the signal and the pump beam illumination. We analyze the spatial distribution of beam intensity in these logic gates using a finite-difference beam propagation method (FD-BPM) and the crosstalk between adjoining pixels is examined from the result. We also experimentally verify that the XOR-, OR-, and AND-gates are realized in the same optical setup. (c) 2007 The Optical Society of Japan.

    This paper presents a new proposal for a mutually pumped phase conjugate mirror (MPPCM) using cross polarization. In the cross polarized MPPCM, two light beams, whose polarizations are orthogonal to each other, incident on a photorefractive crystal, Causing photorefractive interaction to generate phase conjugate waves with an orthogonal polarization to an incident beam. The use of Ar+ laser and BaTiO3 crystal in an experiment for the cross polarized MPPCM found that diffraction efficiency for an extraordinary beam is about 20%. As opposed to a conventional parallel polarized MPPCM in which the use of a beam splitter is required to separate a diffraction beam, the cross polarized MPPCM can efficiently extract phase conjugate waves by means of a polarized beam splitter, demonstrating the advantage of substantially improved efficiency.

    In this paper, we propose a tunable optical filter using a photorefractive planar waveguide. The index grating generated by the control beam drops off a part of wavelength components in the wavelength division multiplexed signal beam. It make possible to select the wavelength components of the signal beam by optically adjusting the wave vector of the grating. The photorefractive effect is one of the most efficient nonlinear effects, and therefore the signal beam can be controlled by the relative low beam power. The proposed optical filter can be applied to an active add-drop module when the signal beam is fed back to the module as a control beam. Therefore, it contribute to development of the all-optical network systems. It is also able to apply to photonic label processing technology by multiplexing the index gratings. We investigated the signal beam propagation and the permittivity distribution in the photorefractive waveguide by using a finite dimensional beam propagation method (FD-BPM) and analyzed the filtering property. Considering the two optical setups using the transmission and reflection grating, we compared these performances.

    All-optical interconnections are expected to play an important role in optical computing and neural network systems. Some schemes of the interconnection with a mutually pumped phase conjugate mirror (MPPCM) have been proposed. But it takes long time for reconfiguration of the wiring pattern because the competition among a lot of the index gratings induced by the incident beam and its scattered beams forms MPPCM gradually. In this report, we propose a new optical interconnection by using mutually pumped four-wave mixing (MP-FWM) which is composed of a MPPCM and a degenerate four-wave mixing (FWM). In this method, the two control beams induce the hologram that determines the wiring pattern of the signal beams in the FWM region. On the other hand, the signal beams are transferred to the phase conjugate beam of the one of the control beam through the FWM region by using MPPCM and then the signal beams are diffracted to the desired output channels by the hologram in the FWM region. This scheme can reduce the time to reconfigure the wiring pattern remarkably compared with the conventional interconnection using only MPPCM because the hologram can be reformed by the two control beam arbitrarily. It also can suppress the channel crosstalk that is often generated by the photorefractive fanning effect. This interconnection is effective method to solve the problems of the electrical wiring techniques such as the electro-magnetic interference and the thermal generation. We give the experimental result by using BaTiO3 crystal and Ar+ laser, and investigate the optimum condition of the beams for high connection efficiency.

    We propose an all-optical interconnection with double mutual-pumped phase conjugate mirrors (MPPCM). The bi-directional interconnection is possible by using single MPPCM, however it is difficult to reconfigure the wiring pattern because the incident angle or location of the signal beams must be readjusted to buildup the new communication lines. In our interconnection. the bi-directional connection between channels is formed by the two MPPCMs produced by the illumination of the signal beams and the control beam. Therefore, the wiring pattern can be reconfigured flexibly by changing the spatial distribution of the control beam without any adjustment of the signal beams. In addition, the self-holding of connection can be achieved because the signal beams diffracted by the MPPCM illuminate the other MPPCM and the holograms in MPPCMs are maintained even if the control beam is cut off. It enables the suppression of control beam power consumption. We investigate the connection efficiency of this interconnection in order to estimate the optimum beam splitter reflectivity and intensity ratio of signal beams for obtaining higher connection efficiency and lower coupling strength threshold for the establishment of connection. We also confirm the self-holding of connection experimentally using the BaTiO3 crystals and the Ar+ laser and show that the connection is maintained for several hundred times as long as the time constant of the crystal.

    We propose an all-optical interconnection with cross-polarized double phase conjugate mirrors (CP-DPCMs). In the interconnection, spatially arrayed signal beams from an input port two-dimensionally intersect with control beams from an output port in the photorefiractive crystal (PRC) where polarizations of these two beams are orthogonal each other. The CP-DPCM can function as the switching element by adjusting the intensity ratio of these two beams because it strongly depends on the intensity ratio of crossing two beams whether the CP-DPCM is built up in the PRC or not. Thus the signal beam is diffracted by the CP-DPCM and propagated to the output port, when the intensity ratio of signal beam and control beam is adjusted to proper value for buildup of the CP-DPCM. This technique offers the point-to-point interconnection in two-dimensional plane. It implies the possibility of miniaturization and the integration by stacking the planes with different wiring pattern in layers compared to the conventional interconnections with DPCMs. For configuring the arbitrary wiring pattern, it is important to determine the intensities of the signal beams and the control beams, so we investigate the optimum intensities of these beams for effective switching. We carry out basic experiment on 1x2 interconnection with BaTiO3 and Ar+ laser.

    We propose a bi-directional multi-channel cross-connector for two-way optical communications with array of the photorefractive crystal. The communication channels are connected bi-directionally by double phase conjugation in each photorefractive crystal. The wiring pattern is possible to determine by the beam that controls whether it generates the double phase conjugation in the crystal. This all-optical switching is effective method to solve the problems of the electrical wiring techniques such as the electro-magnetic interference and the thermal generation. We analyze the connection efficiency for coupling strength of the two four-wave mixing interaction region in the double phase conjugation and investigate the intensity of control beams for sufficiently switching. We also experiment on the bidirectional connection switch and estimate the connection efficiency and the transmission efficiency.

    We have proposed the all-optical interconnection, in which the photorefractive four wave mixing(FWM) is used as the core, by full-linear resonator(FR) with a beam splitter(BS) and a self-pumped phase conjugate mirror(CAT). The index grating of the FWM region inside the photorefractive crystal (PRC), which determines the connection pattern, was maintained by the rewriting effect of the input signal beam and the resonance beam between the CAT and the BS. But the power of the resonance beam was wasted by the optical reflection at the crystal surface of the CAT and the PRC. Therefore the rewriting effect of the connection pattern could not be obtained sufficiently. In this report, we propose the integrated full-linear resonator(IFR), in which a self-pumped phase conjugation(SPPC) region and the FWM region are formed in one PRC, to solve this problem. Compared with the conventional FR, the power loss of the resonance beam by the optical reflection can be prevented and the resonance beam can be used efficiently for the maintenance of the connection pattern. We experiment on the 2x2 all-optical interconnection with the IFR by using BaTiO3 crystals and Ar+ laser. It is shown that the maintenance time of the connection pattern can be extended sufficiently by using IFR.

    We propose and demonstrate an all-optical deflection switch with photorefractive duplex two-wave mixing (TWM) in which common grating is shared by the TWM of the two control beams and that of signal beams in a photorefractive crystal. TWM occurs both with the signal beams and with the control beams. By calculating the output intensities of the signal beams, we show that the output intensities of the signal beams are controllable by use of the phase difference of the control beams. We analyze the practical ratio of the intensities of the control beams to those of the signal beams for effective switching. A comparison of the numerical analysis with a basic experiment is given. Qualitative agreement is exhibited. (C) 2001 Optical Society of America.

    We propose an all-optical fault-tolerant holographic memory with two photorefractive crystals. The memory system can automatically detect "dropout" data and rewrite a corresponding data from tire back up crystal. We analyze the temporal response of the memory, and show how tire dropout data are restored automatically([1]).

    We propose an optical demodulator with photorefractive cross-polarized duplex two-wave mixing, in which the phase-modulated signal beam is converted into the intensity-modulated output signal beams. We calculate the intensity variations of the output signal beams when phase-modulated signal beam input to photorefractive cross-polarized duplex two-wave mixing.

    We propose an all-optical switch controlled by the phase difference of the two control beams with photorefractive effect that induce strong nonlinear effect by relatively low beam power. We explain the concept of this switch, and calculate intensity of signal beam at each output port, then show that the switch can work. We also analyze the influence of phase mismatching in order to operate the switch efficiently.

    the recording density. However, an optical
    interferometer is required to detect the phase of the reconstructed signal, which complicates the optical system.
    In this paper, we propose a method to record a complex amplitude-modulated page consisting of multiple intensity-modulated signals with different phase codes. Each intensity-signal is selectively extracted and reproduced by a spatial filter, as a result, it is possible to detect the signal by a camera device directly.

We design phase modulated light consisting of arbitrary complex amplitude components and unnecessary components, and remove unnecessary components by spatial filter and lens. As a result, the desired complex amplitude distribution is reproduced. Since it is unnecessary to add a random phase to the light on imaging plane, speckle noise on reproduction image is suppressed.

    We design new phase pages with the interleaved conventional phase pages for recording Spatial Quadrature Amplitude Modulation signal in holographic memories. By focusing the phase modulation signal for the page with lens, it is possible to separate necessary and unnecessary spectral components for SQAM signal recording and to remove the unnecessary components by a spatial filter. However, if the two spectrum spatially overlap, part of necessary components are lost, and part of unnecessary components are mixed, which cause distortion in the reproduced signal. In this paper, we propose the application of RLL (Run Length Limited) code2 to SQAM signal for suppression of the spectrum spread and sufficient separation of the two components.

By extracting only necessary component, it is possible to generate the SQAM signal with sufficiently identifiable level.
    We demonstrate producing SQAM signal using the interleaved phase page.

    We design new phase pages with the interleaved conventional phase pages for recording Spatial Quadrature Amplitude Modulation signal in holographic memories. By focusing the phase modulation signal for the page with lens, it is possible to separate necessary and unnecessary spectral components for SQAM signal recording and to remove the unnecessary components by a spatial filter. However, if the two spectrum spatially overlap, part of necessary components are lost, and part of unnecessary components are mixed, which cause distortion in the reproduced signal. In this paper, we propose the application of RLL (Run Length Limited) code2 to SQAM signal for suppression of the spectrum spread and sufficient separation of the two components.

    Spatial quadrature amplitude modulation (SQAM) signal whose amplitude and phase are individually modulated to multi-level have been expected to be used for improvement of recording capacity of holographic memory. We have proposed two exposure method (TEM) in which the two holograms for different phase modulated signal is multiplex recorded in the same position and it synthesize the hologram for SQAM signal. In this report, we design new phase pages for TEM by investigating
    the holographic distribution formed in the memory and show it is possible to suppress the amount of monomer consumed wastefully for the recording SQAM signal by using the new phase pages.

    シフトデジタルホログラフィでは,位相の異なる複数のホログラムを合成することにより,物体光の波面を抽出することができる.ただし,設定した精度で位相が調整されていない場合,虚像光や参照光が重複して再生され,像が大きく劣化する.本論文では,位相シフト法の原理から0次光と虚像の重複再生の原因を考察し,これを低減する方法を提案した.各ホログラムのスペクトル強度を求めると,全体的に重なり合うものの,わずかに異なる位置に虚像,実像成分のピークが観測される.このピーク値に着目し,実像に対して虚像が極めて小さくなる条件を探索した.その結果,画像の劣化を低減できることを示した.

     More details

    Award type:Award from international society, conference, symposium, etc.  Country:Japan

    We propose a new method to detect SQAM signals with a complex amplitude signal consisting of multiple SQAM signals. In the reading, two page data are extracted and reproduced from the complex amplitude signal simultaneously. The amplitude and phase are detected from the interference fringe distribution without external optical interferometer. we estimate the bit error rate for multiplexed number of page data.
