Abstract

This paper implements a simple optical method to forecast power output of superlattice multipliers which are subjected to an external GHz-THz field. These results complement a recent study which addressed the harmonic conversion efficiency in semiconductor superlattices by interface roughness design. Applying a strong ac field on such a device pumps energy into the system, which is then converted to radiation at harmonics of the pump frequency. Here we investigate the odd harmonics generation in an unbiased superlattice at room temperature, after excitation by input signals in a wide frequency range which can provided by realistic devices.
