Abstract: An optical space-division switching assembly comprises a distribution assembly consisting of a stack of P distribution plates each with N guides which on the one hand, for each plate, are coupled in common to the end face of an optical element assigned to the plate and belonging to a group of P elements and, on the other hand, for the P plates, communicate with the same side of the stack in N rows of end faces, and an optical selection assembly consisting of a stack of N flat rigid opto-mechanical switches each movable between an optical element assigned to the switch and belonging to another group of N elements and the corresponding row of end faces of the guides of the plates and incorporating P guides having first ends assigned to the individual links between these guides and the corresponding optical element and second ends individually assigned to the P end faces of the guides of the plates of the corresponding row. This assembly provides for the broadcasting of P programs to N subscribers.

Abstract: 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.
