Space division optoelectronic switch device

摘要

The device comprises, for coupling the accesses of N first elements (fa) with the accesses of N second elements (fp) an distributer assembly (10) constituted by a stack of P flat and rigid distribution plates (11) having N waveguides (h) each coupled to the access of one of the second elements (fp) and a concentrator-selector assembly (20) constituted by a stack of N flat and rigid concentration and selection plates (21) having P waveguides and including an integrated strip (31) of P photodiodes which are coupled to the ends of the P waveguides, said assemblies being assembled to each other to couple the individual waveguides together. It is particularly applicable to optically broadcasting P programs to N subscribers.
