Terahertz generation and power limits in In0.53Ga0.47As photomixer coupled to transverse-electromagnetic-horn antenna driven at 1.55 µm wavelengths

Abstract

We report continuous wave generation at frequencies up to 2 THz using ion-irradiated In0.53Ga0.47As photomixers coupled to transverse-electromagnetic-horn antennae driven at 1.55 m wavelength. Output powers up to 0.1 W at 700 GHz have been achieved. The dependence of the output power on incident optical power and the bias voltage is analyzed in the both regimes of Ohmic transport and recombination-limited transport. The fundamental limitations of the performance of the photomixer devices based on photoconductive phenomenon in recombination-limited transport are analyzed
