Abstract
We investigate a waveguide-integrated plasmonic graphene photodetector operating based on the hot carrier either photo-thermoelectric or photo-bolometric effect, which is characterized simultaneously by high responsivity on the scale of hundreds of A/W and high speed on the scale of 100’s of GHz. The proposed detector configuration is based on a hybrid waveguide that allows for efficient absorption in graphene over a short distance and subsequently a large change of conductivity. The results demonstrate the potential of graphene for high-speed communication systems.
