A Distributed light projection device, including: one or a plurality of waveguides; and above each waveguide, a plurality of extraction cells coupled to distinct portions of the guide, each extraction cell including first and second stacked diffraction gratings.

Distributed light projection device

The invention relates to a photonic circuit for attenuating the amplitude of an optical signal, comprising a Mach-Zehnder interferometer for coupling an input waveguide () and an output waveguide (), said interferometer comprising a modulation section (SM) which includes a first waveguide (), a second waveguide () and a phase shifter () configured to introduce a phase difference between a first optical signal circulating on the first waveguide and a second optical signal circulating on the second waveguide. The first and second waveguides are arranged in two distinct parallel layers and the phase shifter is a thermo-optical phase shifter arranged to preferentially act on one of the first and second waveguides.
