Paper Abstract

A high-quality microwave signal is generated by heterodyning two diode-laser-pumped Nd:YAG lasers. A III-V semiconductor optical waveguide containing a doping superlattice is used to manipulate the phase and amplitude of one of the laser outputs before they are mixed. This manipulation appears directly as a corresponding change in the phase and amplitude of the heterodyne microwave signal. Results are presented from near dc to 52 GHz. Phase changes as large as 8 pi, and amplitude changes as large as 42 dB have been induced by means of a 1.2-mm-long optical waveguide and less than 3 V of control voltage.
