    Abstract: The present disclosure relates to shaping of optic beams at the inputs/outputs of a photonic chip, the spectral widening of the light coupled to this chip, and a method for manufacturing the chip. The photonic chip includes a light guiding layer supported by a substrate. The chip includes at least one light guiding structure made of silicon coupled on one side to a vertical coupler and on another side to an optical component integrated in the light guiding layer. The photonic chip has a front face on the vertical coupler side and a rear face on the substrate side. A collimation structure of digital lens type is integrated at the level of the rear face to collimate the mode size of the light beam incident on the lens and coming from the vertical coupler.

    Abstract: A PVT detection circuit including: first and second transistors of a first conduction type each having its control node coupled to a control line, the first and second transistors being configured such that the variations in their threshold voltages as a function of temperature and/or process are different from each other; and an amplifier coupled to a second main conducting node of each of the first and second transistors and configured to amplify a difference in the currents conducted by the first and second transistors in order to generate an output signal.

    IPC: H01L27/146 ,  H01L31/101

    Abstract: The invention relates to a method for manufacturing a photodetector able to operate for the photodetection of infrared electromagnetic waves, comprising a stack of thin layers placed on top of one another. The method includes obtaining a first assembly (E1) of stacked layers, forming a detection assembly, comprising a first substrate layer, a photoabsorbent layer, a barrier layer and at least one contact layer, and a second assembly (E2) of stacked layers forming a reading circuit, comprising at least one second substrate layer and a multiplexing layer. The first and second assemblies are glued between the contact layer of the first assembly and the multiplexing layer of the second assembly. Etching through the second assembly makes it possible to obtain a plurality of interconnect vias, then p or n doping of zones of the first contact layer of the first assembly through the interconnect vias.
