  • AVALANCHE PHOTODIODE
    Publication number: 20230178676
    Abstract: An avalanche photodiode includes a stack of layers. The stack of layers includes an avalanche diode (of PN or PIN type) and a layer having quantum dots located therein. The stack of layers further includes: a charge extraction layer over the layer which includes quantum dots; a transparent conducting layer over the charge extraction layer; and an insulating layer over the transparent conducting layer. The quantum dots includes ligands formed by molecules of dopants.

  • OPTICAL DEVICE
    Publication number: 20220268965
    Abstract: An optical device includes a layer having a face configured to be traversed by light at an operating wavelength. The face of the layer includes a fractal structure lacking rotational symmetry such as a fractal structure that corresponds to a fractal expressed in an L-system. The fractal structure is formed by recesses that penetrate into the layer from the face. The recesses have a depth which is less that a thickness of the layer.

  • System for converting thermal energy into electrical power
    Patent number: 10075102
    Abstract: A system for converting thermal energy into electrical power includes a temperature-sensitive element held in a frame by its two ends between a heat source and a cold source producing a thermal gradient. A piezoelectric element is positioned between the frame and at least one end of the temperature-sensitive element. The temperature-sensitive element is configured to deform cyclically between two states under the action of the thermal gradient. With each cyclic deformation, a stress is applied to the piezoelectric element via the one end.
