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： The invention relates to a method for manufacturing a waveguide (40) including a semiconducting junction (23). The method comprises the following steps: providing a support (10) comprising a semiconducting layer (20) having a first part (21) of a first conductivity type ; protecting the first part ; selectively implanting a second conductivity-type dopants in a second part (22) of the semiconducting layer (20) adjacent to the first part (21, 221). The concentration of second conductivity-type dopants in the second part (22, 222) is greater than the one of first conductivity-type dopants in the first part (21, 221). The method further comprises the steps of: diffusing second conductivity-type dopants in the first part (21, 221) to form a semiconducting junction (23, 223) in the first part (21, 221), and partially etching the semiconducting layer (20, 200) to form the waveguide (40, 240) in the first part (21, 221), the protection of the first part (21, 221) being used so that the semiconducting junction (23, 223) is included in the waveguide (40, 240).

摘要： An optical particle detector is configured to simultaneously detect at least two particles within a useful detection volume. The detector includes a retina capable of receiving light rays scattered by the particles and a dark reticle interposed between the useful detection volume and the retina. The dark reticle includes at least one optical aperture allowing a passage towards the retina of a part of first scattered light rays and of a part of second scattered light rays, and an opaque surface on a periphery of the at least one aperture, preventing a passage towards the retina of another part of the first and second scattered light rays so as to project onto the retina first and second scattering diagrams separated from each other.

摘要： A laser includes a distributed Bragg minor and is configured to emit monochromatic light radiation along a longitudinal direction. The laser has layers, stacked along a first transverse direction normal to the longitudinal direction and made of III-V materials, including an active region configured to emit the radiation. The mirror is formed by periodic lateral corrugations which extend mainly along the longitudinal direction and having a dimension along a second transverse direction normal to the longitudinal direction. The lateral corrugations of the Bragg minor extend from a top surface of the waveguide pattern along the first transverse direction on a height strictly less than the depth, at which the active region is located starting from the top surface, such that a portion of lateral flanks of the waveguide is free of any lateral corrugations at the active region.

摘要： A particle detector includes at least one resonant cavity partially formed at least by a first reflector, a second reflector disposed at a distance from the first reflector and a channel located between the first and second reflectors, the channel being intended to receive at least one fluid comprising particles and to receive at least one light radiation; and at least one detection system having at least one photodetector. The particle detector is configured so that a portion of the light radiation present in the channel escapes from the cavity throughout the second reflector and reaches the detection system, thereby enabling the at least one photodetector to detect leakage of the cavity. The second reflector is a photonic crystal membranes PCM based reflector.
