Coherent mixing of optical radiation from a tunable CW dye laser and a stabilized HeNe laser was used to generate broadband microwave signals beyond the Ka band in FETs, HEMTs, and the related devices. Comparing with direct modulation of the light signal, this technique enhances photoconductivity and frequency stability.
