A solid-state, surface-emitting, optical device such as a light emitting diode (LED) or vertical cavity surface emitting laser (VCSEL) has a body of optical gain medium overlying a high reflectivity distributed BRAGG reflector (DBR) mirror which is carried on part of an underlayer. The gain layer is part of an epitaxial layered structure extending from the underlayer over the mirror.
