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.
