    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.

    Abstract: An optoelectronic device includes a photodiode. At least a portion of an active area of the photodiode is separated from a neighboring photodiode by a first wall including a conductive core and an insulating sheath and by a second optical insulation wall. The first wall and second optical insulation wall further extend parallel to each other and separate the active area from a memory area of the photodiode.
