摘要： A hologram with a dynamically controlled diffraction efficiency and enhanced signal-to-noise ratio is recorded in ferroelectric photorefractive materials, such as strontium barium niobate (Sr.sub.x Ba.sub.1-x Nb.sub.2 O.sub.6) (SBN), BSTN, SCNN, PBN, BSKNN, BaTiO.sub.3, LiNbO.sub.3, KNbO.sub.3, KTN, PLZT and the tungsten bronze family. The diffraction efficiency of the hologram is dynamically controlled by applying an electric field along the polar axis of the ferroelectric photorefractive recording medium. Electrically controlled diffraction is used in conjunction with hologram fixing and operation of the material at a temperature in the vicinity of or above its Curie temperature to additionally provide prolonged, low-noise readout. The general methods for recording and reconstructing a hologram (or a set of multiplexed holograms) using these techniques is disclosed. A plurality of configurations employing the improved hologram are disclosed, including an optical crossbar switch in guided-wave and free-space formats that can function as a component in a variety of parallel optical processing systems, a reconfigurable dynamic wavelength filter, and a page-based holographic data storage system.

摘要： Near-field sub-wavelength C-apertures provide enhanced spatial resolution and power throughput by increasing the normalized resonant wavelength of the aperture. These improved apertures are characterized by the use of improved geometric proportions for C-apertures, filling the aperture with high-index material, designing aperture thickness to produce longitudinal transmission resonance, and/or tapering the aperture in the longitudinal direction to achieve impedance matching. Apertures according to the present invention may be used for many technological applications in various portions of the electromagnetic spectrum. Exemplary applications to high density optical data storage and optical particle trapping and manipulation are described.

摘要： An encryption method and apparatus for holographic data storage are disclosed. In a system using orthogonal phase-code multiplexing, data is encrypted by modulating the reference beam using an encryption key K represented by a unitary operator. In practice, the encryption key K corresponds to a diffuser or other phase-modulating element placed in the reference beam path, or to shuffling the correspondence between the codes of an orthogonal phase function and the corresponding pixels of a phase spatial light modulator. Because of the lack of Bragg selectivity in the vertical direction, the phase functions used for phase-code multiplexing are preferably one dimensional. Such phase functions can be one-dimensional Walsh functions. The encryption method preserves the orthogonality of reference beams, and thus does not lead to a degradation in crosstalk performance.
摘要翻译： 公开了一种用于全息数据存储的加密方法和装置。 在使用正交相位码复用的系统中，通过使用由单一运算符表示的加密密钥K调制参考波束来加密数据。 实际上，加密密钥K对应于放置在参考光束路径中的扩散器或其他相位调制元件，或者改变正交相位函数的代码与相位空间光调制器的相应像素之间的对应关系。 由于在垂直方向上缺乏布拉格选择性，所以用于相位码复用的相位函数优选地是一维的。 这样的相位函数可以是一维沃尔什函数。 加密方法保留参考光束的正交性，因此不会导致串扰性能下降。

摘要： A method for encoding and decoding digital data for storage in a holographic medium (12). Digital data, consisting of binary data (B.sub.i) or grey scale data (A.sub.i), is encoded in bit groups or digit groups (B.sub.k, A.sub.k) containing at least k=1 bits or digits, respectively, by assigning to each bit group (B.sub.k) one reference bit (B.sub.r) and to each digit group (A.sub.k) two reference digits (A.sub.r1, A.sub.r2), assigning the bits of group (B.sub.k) to information bits (B.sub.j), assigning the digits of group (A.sub.k) to information digits (A.sub.j), assigning the reference bit (B.sub.r) and information digits (B.sub.j) to a reference pixel (P.sub.r) and information pixels (P.sub.j) chosen from pixels (24) of a holographic signal modulator (18), and assigning the reference digits (A.sub.r1, A.sub.r2) and information digits (A.sub.j) to reference pixels (P.sub.r1, P.sub.r2) and information pixels (P.sub.j) chosen from pixels (24) of the holographic signal modulator (18). Storing all pixels (24) by illuminating the holographic signal modulator (18) with a signal beam (22) which impresses upon the signal beam (29) pixels (24), guiding the signal beam (22) to the holographic medium (12) and storing the pixels (24) by directing a reference beam (26) at the holographic medium (12) from a predetermined angle .beta. and at a predetermined part of the holographic medium (12). Decoding the encoded binary data (B.sub.i) and encoded grey scale data (A.sub.i) by aiming the reference beam (26) at the holographic medium (12) at the same angle .beta. and location as during storage, recovering pixels (24) and recovering from them using a decoding unit (38) reference bits (B.sub.r) and information bits (B.sub.j) for each bit group (B.sub.k), and recovering reference digits (A.sub.r1, A.sub.r2) and information digits (A.sub.j) for each digit group (A.sub.k). Reconstructing the original binary data (B.sub.i) by differentiating the binary values of bits (B.sub.r) and (B.sub.j). Reconstructing the grey scale data (A.sub.i) by differentiating the reference digits (A.sub.r1, A.sub.r2) to obtain a benchmark (D.sub.r) and applying a binary operation on the benchmark (D.sub.r) and each of the information digits (A.sub.j).
