Abstract

An optical data processing unit for parallel processing operation is based on one or more successively mutually superimposed optical memory plates and light directing members for controlling the application of input optical data to the memory plates, each memory plate being formed of a planar array of electro-optical memory elements capable of memorizing optical data incident thereon and emitting corresponding optical data thereafter. The memory elements preferably consist of bistable semiconductor laser diodes, enabling an extremely high speed of data processing and logic function switching to be achieved.
