Abstract: The present disclosure relates to a device for converting an optical pulse to an electronic pulse includes a photoresistor having first and second terminals and being capable of receiving a pulsed laser signal arising from a mode-locked laser source The first terminal is linked to a node for applying a reference potential via a resistive element and a capacitive element connected in parallel. The second terminal is connected to a node for applying a supply potential.

Abstract: In accordance with an embodiment of the present invention, an optical switch includes a photoconductor body including a first edge and an opposite second edge, a first end and an opposite second end. The first edge is configured to receive an electrical input signal and the second edge is configured to deliver an electrical output signal. The photoconductor body is configured to have an electrically ON state that is activated by an optical signal and an electrically OFF state that is activated by an absence of the optical signal. A direction from the first end to the second end defines a longitudinal direction. The direction from the first edge to the second edge defines a first direction that is orthogonal to the longitudinal direction. A first dimension between the first edge and the second edge along the first direction decreases from the first end to the second end.

Abstract: The present disclosure relates to a device for generating a clock signal including a first photoresistor coupling a capacitive output node to a node receiving a first potential. A second photoresistor couples the capacitive node to a node receiving a second potential. The first and second photoresistors receive the same optical pulses of a mode-locked laser at instants in time offset by a first delay.
