Abstract (en)
[origin: WO2004003610A2] The invention concerns a device for directional and wavelength selective optical coupling, formed in a photonic crystal (12) and comprising two parallel waveguides (14, 16) separated by a coupling zone (18) for extracting a specific frequency from a signal (30) injected in fundamental mode of a waveguide (14) and for recovering said frequency in output (34) of the other waveguide (16), by coupling between fundamental mode and high order mode of each waveguide.
