Abstract: An optoelectronic component includes an optical transducer made of III-V semiconductor material and an optical scanning microelectromechanical system comprising a mirror. The optical transducer and the optical scanning microelectromechanical system are produced on a common wafer comprising at least a first layer made of silicon or silicon nitride with a thickness of less than one micron and wherein at least the mirror and its holding springs are produced. In a first variant, the mobile parts of the optical scanning microelectromechanical system are produced in various layers of silicon. In a second variant, the mobile parts of the optical scanning microelectromechanical system are produced in the layer of III-V semiconductor material.

Abstract: A lidar system includes a laser assembly comprising at least one laser source, the laser assembly being configured to emit a first beam comprising a first comb of separate wavelengths and a second beam comprising a second comb of separate wavelengths different from those of the first comb, the lidar system comprising an optical detecting system for detecting radiation emitted by the laser assembly and reflected by a scene to be observed, wherein the lidar system also comprises, inter alia: a first diffractive optical component configured to direct the first beam toward the scene to be observed in a plurality of different directions for each wavelength of the first comb.

Abstract: A LIDAR system includes at least one laser source and an optical detection system for detecting radiation emitted by the laser source and reflected by a scene to be observed, wherein the laser source is designed to emit simultaneously at n>1 separate wavelengths ?i, i?[1,n]; the LIDAR system also comprises a diffractive optical component configured to direct the radiation emitted by the laser source to the scene to be observed in a different direction for each the wavelength in a simultaneous manner, the directions being located in a same plane xz; and the optical detection system comprises at least one photodiode arranged so as to be illuminated by the radiation reflected by the scene to be observed, as well an optical system, which is configured to direct laser radiation, emitted by the or another laser source and having a wavelength ?0 which is different from the n wavelengths ?i, to the one or more photodiodes, such that the one or more photodiodes generate a signal comprising the beats of the waveleng
