<p>1. An optical interconnection apparatus for recording interference fringes caused between coherent signal input light (113,114,115) and reference light (112) on a hologram recording medium (111) to form a hologram and for selectively reconstructing output light (117,118,119) from the hologram to effect optical interconnection between the input and output light, characterized in that the apparatus includes an optical system which generates signal input light having optical shutter means (108,109,110) for controlling blockage and transmission of light so as to generate at least one signal input light beam (113,114,115), and the hologram recording medium comprises a light addressed liquid crystal light valve (111) composed of a photoconductive layer (124), a pair of liquid crystal alignment layers (122a, 122b), a ferroelectric liquid crystal layer (123) having a bistable memory characteristic between its reflectivity and an applied voltage, means for applying the voltage, and a pair of transparent substrates (120a,120b). <IMAGE> <IMAGE></p> |
