ABSTRACT:
Optical transmitters are disclosed, one example of which includes a vertical cavity surface emitting laser that includes a substrate upon which a lower mirror is disposed. In this example, a spacer is disposed between the lower mirror and an active region. Another spacer separates the active region and an upper mirror. The upper mirror includes an oxide insulating region that is damaged by ion implantation so that desirable effects are achieved with respect to lateral sheet resistance, and quantum well recombination centers in the active region.
