Optical disks in optical computing

COMPCON Spring '91 Digest of Papers, 2002
Two optical-disk based architectures are described. The first is an optical implementation of the radial basis function approach for handwritten character recognition. The second system is an optoelectronic neural network implementation with electronic neurons, electronic synapses, and optical-disk-based weight storage.

Optically tunable optical filter

Applied Optics, 1995
We experimentally demonstrate an optically tunable optical filter that uses photorefractive barium titanate. With our filter we implement a spectrum analyzer at 632.8 nm with a resolution of 1.2 nm. We simulate a wavelength-division multiplexing system by separating two semiconductor laser diodes, at 1560 nm and 1578 nm, with the same filter.
