Abstract

Diode lasers Injection-locked oscillators Intensity modulation Laser excitation Laser feedback Masers Microwave oscillators Optical feedback Optical modulation Semiconductor lasers
Large-signal microwave modulation of laser diodes excite harmonics which have been exploited to achieve optical injection locking of multiple millimeter wave oscillators. Experimental results of large-signal modulation of laser diodes with optical feedback are presented. The external cavity increases the optical intensity modulation depth of both the fundamental (3.456GHz) and its harmonics by approximately 20dB.
