Abstract

The Vertical-Cavity Surface-Emitting Laser (VCSEL) is today considered to be a promising component for a number of applications. Many of these applications would benefit from using a single mode VCSEL. Oxide confined VCSELs small enough only to support the fundamental mode have been fabricated for this purpose. But due to the inability to control the oxide aperture size to within required tolerances of reproducibflity, there is a need for alternative mode stabilizing methods.
