Abstract

An equivalent circuit was used to study the generation of terahertz (THz) radiation from low-temperature-grown gallium arsenide (LTG-GaAs) photoconductive antenna (PCA) device which takes into account the generation, transport, and screening effects on the photogenerated carriers. A parametric investigation on the effects of laser excitation power, pulse duration, carrier lifetime, and mobility on the radiated THz emission was performed. These results provide insights on the design optimization of intense THz sources.
