Abstract:
A photodetector includes a waveguide on a substrate, and a photodetection portion connected to the waveguide. The photodetection portion includes a first semiconductor layer, graphene on the semiconductor layer, and a second semiconductor layer on the graphene. A first electrode and a second electrode separated from the first ridge portion and electrically connected to the graphene.
