Optical routers using angular position amplification modules

An optical routing device for coupling each of a plurality NE of incoming optical channels (1) to any one of a plurality NS of outgoing optical channels (5) and for directing each of the optical beams entering via the incoming optical channels toward any of the NS outgoing optical channels, NE and NS each being an integer greater than 1, the optical routing device comprising:

• an input module (40) having NE optical inputs, that is designed to shape each of the beams entering via the incoming optical channels so as to obtain a plurality of shaped optical beams (112);
• an input deflection module (30) designed to generate, for each of the inputs, a number PTN of different angular deflection positions at least equal to the number NS of outgoing optical channels, the input deflection module comprising NE lines each having a plurality of deflection elements arranged in cascade and each able to adopt a plurality of angular deflection configurations numbering less than the number PTN, each said deflection element being, in each line, coupled to a preceding said deflection element by an optical conjugation element designed to carry out object-to-image conjugation with a magnification G between said deflection element and the preceding said deflection element;
• a linking module (50) designed to collate, in a one-to-one manner, the PTN angular deflection positions of each of the inputs with respect to PTN spatial focusing points respectively, this module being designed to generate PTN intermediate optical beams;
• an output deflection module (35) having PTN inputs, that is designed to intercept the PTN intermediate optical beams and to generate, from the intermediate optical beams, NS output beams, the output deflection module comprising NS lines each comprising a plurality of angular deflection elements in cascade and able to adopt a plurality of angular deflection configurations numbering less than the number of NS, each said deflection element being, in each line, coupled to a preceding said deflection element by an optical conjugation element designed to carry out object image conjugation with a magnification G between this deflection element and the preceding one;
• and
• an optical output module (45) designed to shape each of the NS output beams so as to be able to apply them to the NS outgoing channels.
