Abstract

We propose dielectric nanoantenna enhanced compact room-temperature operating hybrid photoconductive antennas (PCAs). Dielectric nanostructures in the PCA gap are deposited by focussed ion beam (FIB) and electro nanolithography methods. The resulting nanoantenna enhanced metasurfaces show 5-fold increase in pump radiation absorption, thus leading to THz generation enhancement.
