Abstract

Injection locking of multiple semiconductor lasers to a single master laser is a promising technique for increasing the amount of coherent optical power available from this highly efficient light source. With FM sideband injection locking,¹ the technique can also be used for frequency multiplexing for optical fiber communications and to generate narrowband microwave signals.² Injection locking of a single semiconductor slave laser (SL) by a master laser (ML) has been extensively studied.^3-4 Injection locking of many slave lasers, however, makes the requirements of wavelength matching between the lasers and relative frequency stability more difficult to achieve.
