Abstract

Terahertz lies at the juncture between RF and optical electromagnetism, serving as a transition from mm-Wave to infrared photonics. Terahertz technology has been used for industrial quality control, security imaging, and high-speed communications, and often generated through optoelectronic solutions by using photoconductive antennas. In this paper, Multiphysics simulations on semi-insulating GaAs, graphene-enhanced photoconductive antennas are conducted to effectively decouple optical responses of semiconductor carrier generation/drift from Terahertz radiation computation, which provides a comprehensive and integrated platform for future terahertz photoconductive antenna designs.
