Abstract

We demonstrate, for the first time, an all-optoelectronic continuous-wave terahertz photomixing system that uses low-temperature grown InGaAs devices both for emitters and coherent homodyne detectors. The system is compatible with fiber-optic excitation wavelengths, and we compare the performance to the more common LT-GaAs photomixers.
