Abstract

A new technique for generating millimeter‐wave signals from a semiconductor laser is presented. A 32‐GHz signal is generated using a multi‐section semiconductor laser, which is operated under continuous‐wave conditions and by injecting optical pulses at a repetition rate equal to the fourth subharmonic (8 GHz). The generated millimeter‐wave signal exhibits a large subharmonic suppression ratio (>17 dB), a large‐frequency detuning range (>300 MHz), low levels of phase noise (−77.5 dBc/Hz), and large locking (>400 MHz). © 2004 Wiley Periodicals, Inc.
