摘要： The invention is an electromechanical resonator, comprising a fixed portion and an oscillator oscillating at a resonant frequency and comprising a fluidic channel. The channel defines a fluidic circuit, can receive a fluid, and can be deformed at the resonant frequency. The resonator includes a waveguide, defining a photonic circuit, guiding a light wave between an input and an output of the waveguide and being able to be deformed at the resonant frequency. The waveguide input can be connected to a light source and the waveguide output can be connected to a photodetector able to form a signal representative of the light wave propagated by the waveguide towards the photodetector, the light wave being modulated at a frequency dependent on the resonant frequency. A variation in a mass of the fluid, inducing a variation in the resonant frequency, may be detected via the signal formed by the photodetector.

摘要： A method for forming a Bragg reflector includes after forming first trenches in the stack, which are intended to form structures of the distributed Bragg reflector, forming a sacrificial interlayer at least in the first trenches, depositing a second masking layer at least inside the first trenches, forming second trenches intended to form sidewalls of the laser, removing the second masking layer from inside the first trenches, removing said sacrificial interlayer so as to remove, by lift-off, residues of the second masking layer that remain inside the first trenches, and filling said first trenches with at least one metal material.

摘要： A method for producing a waveguide including a germanium-based core and a cladding is provided, the method including a step of “low temperature” depositing of a shell after forming the core by engraving, such that the deposition temperature is less than 780° C., followed by a step of “high temperature” depositing of a thick encapsulation layer. The shell and the encapsulation layer at least partially form the cladding of the waveguide. Optionally, a step of annealing under hydrogen at a “low temperature”, less than 750° C., precedes the deposition of the shell. These “low temperature” annealing and depositing steps advantageously make it possible to avoid a post-engraving alteration of the free surfaces of the core during the forming of the cladding which is less germanium-rich.

摘要： A method for analysing a sample uses a resonant support having a surface on which a plurality of separated photonic crystals extends. At least two crystals are configured to capture the same analyte. A resonance wavelength associated with each crystal varies with an amount of analyte in contact with the crystal. The wavelengths define a resonance spectral band between 200-1500 nm. The transmission/reflection of the light is maximum at an associated resonance wavelength. The method includes: illuminating the support in the resonance spectral band, the intensity of the lamination being variable in band; acquiring a measurement image using an image sensor, the image having different regions-of-interest each optically coupled to a photonic crystal; using a reference image representative of an image acquired by the image sensor, when the support is illuminated in the resonance spectral band in a reference configuration; and comparing the measurement image with the reference image.

摘要： A PIN structure semiconductor optical receiver includes first and second electrical contact layers and an intrinsic layer disposed between them. The intrinsic layer includes a stud having a stud axis and a stud cross-section. The first and second contact layers have dimensions in a plane perpendicular to the stud axis that are greater than the stud's cross-section. These layers are also elongated and have longitudinal axes offset angularly relative to each other to minimize facing areas of said electrical contact layers.
