Abstract

Full electrodynamic Monte Carlo simulations have been performed to evaluate the electrical response of nanoscale GaAs photomixers driven by dual laser beams. Low temperature grown GaAs structures are shown to be capable of providing terahertz signals. Photocurrent results indicate an advantage in increasing input laser power. However, bulk heating due to carrier trapping and phonon emission is shown to be fairly significant, and should set a natural limit to laser input scaling. Finally, the simulations reveal that special antenna structure would be necessary for the efficient coupling and transmission of radiative energy.
