摘要： A signal-distributing device that includes an arrayed-waveguide-grating demultiplexer and at least one receiving module. Each receiving module includes a multimode interference coupler and two output waveguides, the multimode interference coupler being located between the arrayed-waveguide-grating demultiplexer and the two output waveguides. The multimode interference coupler is configured to distribute, to the two output waveguides, an optical signal delivered by the arrayed-waveguide-grating demultiplexer. Such a device allows wavelength shifts in the signal delivered by a set of one or more sensors, in particular Bragg grating reflectors inscribed in a given optical fibre, to be measured. It allows a wavelength shift to be measured with a high linearity and a signal-to-noise ratio.

摘要： An optomechanical system including a guide structure, to guide a light beam; and two waveguide segments. Each guide structure include beams that together form two combs partially nested one in the other. At least one beam is free to move in translation along an axis orthogonal to the long axis of the guide structure. A displacement into an optical phase shift, while limiting additional effects on the intensity.

摘要： An opto-mechanical resonator including a waveguide formed by a plurality of first strips spaced apart from one another; and two mirrors disposed facing one another, which mirrors are optically reflective over at least part of a guide wavelength range of the waveguide. The waveguide extends between the two mirrors, and forms therewith an optically resonant cavity. At least part of the waveguide is held such that it is suspended over a substrate by at least one deformable mechanical element.
