Abstract

An experimental study of a vertical-cavity surface-emitting laser with frequency-selective feedback is reported. We show that we can force the laser to emit in its fundamental transverse mode or in a higher order transverse mode and that we can also control the polarization emitted in the fundamental one. We obtain single fundamental-mode operation within a large range of injection current values (almost /spl ap/2.5 I/sub th/) and a maximum optical power of 2.7 mW. In this current range, the output is found to be stable.
