ABSTRACT:
A resonant-cavity optical device, eg a vertical cavity surface emitting laser, has a substrate upon which are provided a Bragg reflector multilayer bottom mirror, a semiconductor lower spacer region, an active region, and a dielectric region which surrounds the bottom mirror, the active region and the lower spacer region. An upper spacer region and a top mirror are provided on top of the active region. The top mirror has a window in which a metal terminal is provided. The terminal is in direct contact with the upper spacer region which is formed of a transparent electrically conducting oxide, eg indium tin oxide.
