    Abstract: A pixel includes a first electrode layer on an exposed surface of an interconnection structure and in contact with a conductive element of the interconnection structure. An insulating layer extends over the first electrode layer and includes opening crossing through the insulating layer to the first electrode layer. A second electrode layer is on top of and in contact with the first electrode layer and the insulating layer in the opening. A film configured to convert photons into electron-hole pairs is on the insulating layer, the second electrode layer and filling the opening. A third electrode layer covers the film.

    Abstract: The present disclosure relates to a device that includes a photodiode having a first terminal that is coupled by a resistor to a first rail configured to receive a high supply potential and a second terminal that is coupled by a switch to a second rail configured to receive a reference potential. A read circuit is configured to provide a pulse when the photodiode enters into avalanche, and a control circuit is configured to control an opening of the switch in response to a beginning of the pulse and to control a closing of the switch in response to an end of the pulse.

    Abstract: A three-dimensional photonic integrated structure includes a first semiconductor substrate and a second semiconductor substrate. The first substrate incorporates a first waveguide and the second semiconductor substrate incorporates a second waveguide. An intermediate region located between the two substrates is formed by a one dielectric layer. The second substrate further includes an optical coupler configured for receiving a light signal. The first substrate and dielectric layer form a reflective element located below and opposite the grating coupler in order to reflect at least one part of the light signal.
