Abstract[English]
A photodetector (PD), comprises: a photonic layer (1) which includes a widening section (12) followed by a wide section (13), wherein the widening section (12) is configured to receive an optical signal (oS) and to distribute optical power of the optical signal (oS) to the wide section (13); a spacer layer (2) which is in contact with the wide section (13); a 2D material layer (3) which is in contact with the spacer layer (2); a plasmonic layer (4) which is in contact with the 2D material layer (3) and includes a plurality of plasmonic resonators (411, 421) which are connected via contact lines (412, 422) to connector lines (413, 423), wherein the connector lines (413, 423) enable to measure charge carriers which are generated upon receipt of the optical signal (oS).[French]
Un photodétecteur (PD) comprend : une couche photonique (1) qui comprend une section d'élargissement (12) suivie d'une section large (13), la section d'élargissement (12) étant configurée pour recevoir un signal optique (oS) et pour distribuer la puissance optique du signal optique (oS) à la section large (13) ; une couche d'espacement (2) qui est en contact avec la section large (13) ; une couche de matériau 2D (3) qui est en contact avec la couche d'espacement (2) ; une couche plasmonique (4) qui est en contact avec la couche de matériau 2D (3) et comprend une pluralité de résonateurs plasmoniques (411, 421) qui sont connectés par l'intermédiaire de lignes de contact (412, 422) à des lignes de connexion (413, 423), les lignes de connexion (413, 423) permettant de mesurer des porteurs de charge qui sont générés lors de la réception du signal optique (oS).
