Abstract
An optical routing device for coupling each of a plurality NE of optical incoming channels (1) to one of a plurality NS of optical output channels (5) and for orienting each of the optical beams coming through the incoming channels to any one of the NS optical output channels, includes: an input module including NE optical inputs, for shaping each beam, so as to obtain a plurality of shaped optical beams; an input deflection module for generating for each input a number PTN of different positions of angular deflection at least equal to the number NS of optical output channels; a linking module for assembling in bi-unique manner on PTN spatial focusing points, respectively the PTN angular deflection positions of each; an output deflection module having PTN inputs for intercepting PTN intermediate optical beams; and an optical output module for shaping each NS output beam.
