Abstract

Millimeter-wave sources at 60 GHz have been demonstrated using optically driven heterojunction bipolar transistors (HBTs) configured as photodetectors. Two techniques were used to optically generate the millimeter waves: the mixing of two continuous wave lasers and the mode locking of a semiconductor laser. The millimeter-wave power generated from these two configurations was radiated into free-space using integrated planar twin dipole antennas and heterodyne detected with signal to noise ratios>40 dB. As part of these experiments, the DC optical gain and quantum efficiency of the HBT photodetectors were determined.<>
