Abstract:
An optical beam router comprising a series of optical input channels and a series of optical output channels, two optical index spatial modulation cells capable of respectively deflecting an optical beam coming out of an input channel and arriving onto an output channel, each series of optical channels being distributed over two dimensions transverse to the direction of the channels and each of the index spatial modulation cells being provided to produce deflections in these two dimensions, characterized in that it includes at least one convergent optical assembly placed overlapping a first of the two cells and whose focus, defined with respect to the light path in the router, is in the vicinity of the plane of the other cell, and in that the or each convergent optical assembly has its optical center on the border of a deflection cell, substantially directly above the center of one side of this cell.
