    摘要: 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) enabling a particular frequency to be extracted from a signal (30) injected in fundamental mode into one of the waveguide (14) and to recover said frequency at the outlet (34) of the other waveguide (16), extraction and injection being performed by coupling between fundamental and high order modes in each waveguide.
