Abstract

Summary form only given. Heterodyne downconversion, or photomixing, of two CW laser beams has proven to be a successful way to generate narrow-band radiation in the terahertz spectral region. For the first demonstration of efficient and frequency-tunable CW photomixing in a low-temperature-grown (LT) GaAs antenna, Brown et al. (1995) mixed the radiation from two independent Ti:sapphire lasers. Instead of two independent Ti:sapphire lasers one would prefer to run a single laser with two-color output. We present experimental data for two dual-color resonator concepts, a linear and a ring concept, respectively.
