Abstract

High power density can be obtained from vertical-cavity surface emitting semiconductor lasers (VCSELs), but the emitting area must be kept small if spatial coherence is desired. We present the result of a theoretical and calculational study of the possibility of placing the gain regions of VCSELs in external cavities to provide mode control over a larger area. A Fabry-Perot or stable resonator with very low loss is required. Several configurations are discussed and evaluated. A ring cavity is the most practical due to its relative lack of sensitivity to misalignment of the mirrors.
