Abstract

The total efficiency of the optical-terahertz conversion ηtotal in photoconductive antennas (PCAs) on the basis of different materials (LT-GaAs and In0.38Ga0.62As) under optical laser excitation at wavelengths of 800 and 1030 nm is studied. It is shown that the photoconductive material factor μτ2 has a significant impact on the magnitude of the THz photocurrent and the value of ηtotal. With the use of electromagnetic modeling, the processes of heat transfer are studied and the power of Joule heating in these PCAs is evaluated.
