DEVICE FOR CROSSING OPTICAL BEAMS, IN PARTICULAR IN AN INTEGRATED OPTICAL CIRCUIT

摘要

A device (400) for crossing optical beams comprises at least first input optical waveguide (402') directed along a first axis, a second optical waveguide (403') directed along a second axis inclined with respect to the first axis, and a photonic crystal (401) having a regular periodicity in an optical crossing region at the intersection of said first and second axis comprises; opposite the first and second input waveguides (402', 403'), a first and a second output waveguides (402", 403") are provided for the exit beams.
