Abstract: Optical system has a passive optical chip on the top surface with a first wave guide and a laser diode arranged on the edge of the chip. The chip has a reflecting structure on the top surface at the wavelength of the laser diode and a thin layer portion powered by the laser diode and covering a part of the first wave guide. The first wave guide input is linked to the laser diode, passing through the reflecting structure. The chip has a second wave guide on the top surface, a first coupler formed by two first portions of the first wave guide not covered by the thin layer portion and situated on either side of the thin layer portion along the optical path, and a second coupler formed by two second portions, respectively of the first and second wave guides, not covered by the thin layer portion.

Abstract: Optical signal emission system comprising a passive optical chip (6) and a laser diode (2) disposed at the boundary of said passive optical chip (6), said passive optical chip (6) being furnished with a reflecting structure (5) in upper surface, of a waveguide (7) in upper surface, passing through said passive optical chip (6), linked to the output of said laser diode (2) and passing through said reflecting structure (5), and of an active or non-linear thin layer portion (8) powered by said laser diode (2), covering a part of said waveguide (7), between said laser diode (2) and said reflecting structure (5).
