Nanoantenna Conjugated Graphene Photodetectors — •Abhinav Raina, Mo Lu, Max Reimer, Vasilii Osipov, Klaus Meerholz, and Klas Lindfors — Department für Chemie, Universität zu Köln, 50939, Köln, Germany

Optical communications is a technology that utilizes light for the wireless transduction of signals. Over the past few decades, the rapid development of nanoscale fabrication techniques has allowed for a significant improvement in the control over the transduction of optical signals. For example, optical nanoantennas have been used in steerable wireless links.[1] In an effort to detect the signals in optical nanoantenna links as an electrical signal, we couple nanoantenna arrays with a graphene photodetector. Such a device would act as a demonstration of tunable, on-chip, wireless transmission and detection of optical signals.
