Abstract

Optoelectronic generation of millimeter-wave (mm) signals attracts increasing amount of interest in applications including wireless mm-wave communication systems and optical feeding of phased-array antennas. Among a number of optoelectronic techniques available for the generation of mm-wave signals such as using mode-locked lasers and using external modulators, heterodyning of two independent lasers is particularly suited for the generation of higher-frequency tunable signals because its operation is not restricted by the cavity resonant frequency or the bandwidth of modulators.
