Abstract :
This work proposes a new type of continuous-wave (CW) terahertz (THz) generation based on vertically integrated LTG-GaAs photomixer and Nanogrid-based transparent top bias-electrode. The THz output power can be increased by higher available photocurrents and smaller device capacitances. A suitable resonant antenna design is proposed.
