<p>A solid-state, surface-emitting, optical device such as a LED or VCSEL has a body of optical gain medium (18) overlying a high reflectivity distributed Bragg reflector (DBR) mirror (14) which is carried on part of an underlayer (13). The gain medium (18) is part of an epitaxial layered structure (15) extending from the underlayer (13) and over the mirror (14).</p> |
