Abstract
A method of fabricating an electrically pumped, long-wavelength vertical cavity surface emitting laser includes epitaxially growing a stack of alternate layers of a first material and a second material on a compatible substrate. A long wave-length active region is epitaxially grown on the stack and a lasing aperture and current confinement volume are defined in the long wave-length active region. A first mirror stack is formed on the long wave-length active region and portions of one of the first material and the second material are removed to form a high reflectivity second mirror stack.
