Abstract

Optical device with superimposed photonic circuits, for coupling to an optical waveguide.Said device comprises a substrate (44) and, on said substrate, an integrated photonic circuit (46) adapted to be coupled to at least one optical waveguide (48) which transmits a light signal (50) and for processing said signal. According to the invention, the circuit comprises two superimposed elementary integrated photonic circuits (52, 54), each of which is adapted to be coupled to a given polarization state of the signal and to process this state. The invention applies particularly to optical telecommunications.
