Abstract

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).
