  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, grapheneenhanced 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
