Dynamic beam deflection using photorefractive gratings in Bi_12SiO_20 crystals

Propagation of Incoherently Coupled Soliton Pairs in Photorefractive Crystals and their Self-Deflection

Propagation of incoherently soliton pairs in photorefractive crystals under steady-state conditions is studied. These soliton states can be generated when the two mutually incoherent optical beams with the same polarization and wavelength incident on the biased photorefractive crystal. Such soliton pairs can exist in bright-bright, dark-dark, gray-gray as well as in bright-dark types. In this p...

Crosstalk in dynamic optical interconnects in photorefractive crystals

Data Storage and Retrieval using Photorefractive Crystals

Adaptive optical networks using photorefractive crystals.

The capabilities of photorefractive crystals as media for holographic interconnections in neural networks are examined. Limitations on the density of interconnections and the number of holographic associations which can be stored in photorefractive crystals are derived. Optical architectures for implementing various neural schemes are described. Experimental results are presented for one of the...
