Planar optical dynamic crossbar switch

A compact dynamic crossbar switch, based on a planar optics configuration, is presented. It consists of a pair of identical planar holographic cylindr ical telescopes, each recorded on a single substrate, and a two-dimensional array (8 x 8) ferroelectric liquid crystal spatial light modulator. The cr ossbar switch can direct the light from any particular source in a one-dime nsional array of 8 sources to a particular detector in a one-dimensional ar ray of 8 detectors. The design of the overall configuration is presented al ong with experimental results. (C) 1999 Society of Photo-Optical instrument ation Engineers. [S0091-3286(99)01108-3].
