摘要: A wavelength demultiplexing device configured so as to spatially distributing the spectral contributions of an incident light beam, when in use, and which includes a linear waveguide and a planar waveguide, formed in a coplanar way and adapted to be optically coupled with one another along a coupling line, by evanescent coupling. Such a device may further include diffraction gratings located in the planar waveguide, to extract light out of the latter.

摘要: An optical device for a biological or chemical sensor includes: an absorption cavity configured to receive a biological or chemical medium; an injection waveguide to inject an analysis light beam into the absorption cavity; and an extraction waveguide to extract a measurement light beam, corresponding to the analysis light beam after transit through the absorption cavity. The absorption cavity has a shape of a right cylinder with an elliptical base. One end of the injection waveguide is placed at a first focus of the ellipse and one and of the extraction waveguide is placed at a second focus of the ellipse. A core of the injection waveguide and a core of the extraction waveguide each have a tip-shaped end, with a constant height in a plane parallel to the generatrix of the right cylinder and a tip-shaped cross section in planes parallel to the base of the right cylinder.

摘要: A photodiode which includes a core of a first waveguide that terminates in a tapered termination that extends above a core, made of germanium or of SiGe, of a second waveguide, a matching strip that extends opposite the tapered termination on one side and opposite the core of the second waveguide on the opposite side, this matching strip being coupled optically to the core of the second waveguide by an evanescent coupling and including a first zone inside which its effective propagation index is equal to the effective propagation index of a second zone of the tapered termination, these first and second zones optically coupling the tapered termination to the matching strip through a modal coupling, and a low-index layer that extends between the matching strip and the tapered termination.

摘要: The object of the invention is a phase modulator including a modulation guide intended to guide die propagation of a light flow, said guide comprising a PN junction extending mainly along the main axis of propagation according to an oscillating continuous function. Advantageously, the oscillating continuous function is defined in such a way that the PN junction covers at least 50% of the light flow between the input and the output of the modulation guide. According to one possibility, the continuous function is sinusoidal. The object of the invention is also a switch and an intensity modulator each comprising a phase modulator.

摘要: A laser source including a germanium-based semiconductor layer, including a suspended membrane formed of a tensilely stressed central portion and including an optical amplification section, and a plurality of tensioning arms. It includes an integrated waveguide, which participates in forming an optical cavity and which is located level with the carrier layer and at distance from the suspended membrane, the waveguide including a coupling section located facing the optical application section, which is suitable for allowing evanescent-wave optical coupling to the latter, and at least one curved section, which extends the coupling section, and which is arranged so that the integrated waveguide is placed at distance, in orthogonal projection, from the tensioning arms.

摘要: An array bolometric detector for detecting an electromagnetic radiation in a predetermined infrared or terahertz wavelength range, including a substrate, and an array of bolometric microplates for the detection of the radiation, suspended above the substrate by support elements. The detector includes a membrane arranged above each microplate, and having patterns having a refractive index smaller than that of the membrane formed therein. The patterns are placed periodically along at least one axis of the membrane, according to a period shorter than or equal to λ n , where λ is a wavelength to be detected and n is the average refractive index of the medium separating the microplate from the membrane. The width of the patterns along the axis increases from a central location of the membrane towards the periphery thereof.
