Method for forming an optoelectronic device having an isolation layer
First Claim
1. A method for forming an optoelectronic device, comprising:
- forming a substrate;
forming a bottom mirror on the substrate, the bottom mirror being at least partially conductive;
forming an active region above the bottom mirror;
forming a top mirror above the active region, the top mirror being at least partially conductive;
defining a gain guide aperture in the top mirror; and
forming, above the top mirror, a substantially dielectric isolation layer, and a resonant reflector, the substantially dielectric isolation layer being interposed between the resonant reflector and the top mirror, and the substantially dielectric isolation layer being formed so as to substantially prevent energy in an evanescent tail of a guided mode associated with the resonant reflector from entering the top mirror.

Abstract
Methods are disclosed for forming optoelectronic devices. In one example of such a method, a substrate is provided and a partially conductive bottom mirror formed thereon. An active region is then formed on the bottom mirror, and a top mirror formed on the active region. A gain guide is then formed in the top mirror. Finally, a substantially dielectric isolation layer, as well as a resonant reflector, are formed on the top mirror. The isolation layer is interposed between the resonant reflector and the top mirror, and the isolation layer is formed so as to substantially prevent energy in an evanescent tail of a guided mode associated with the resonant reflector from entering the top mirror.
