ABSTRACT:
An annular waveguide VCSEL for achieving a stable high power single high order mode output including a first mirror stack with mirror pairs in a Al.sub.x Ga.sub.1-x As/Al.sub.y Ga.sub.1-y As material system lattice matched to an active region. The active region includes an active structure sandwiched between a first cladding region adjacent the first mirror stack and a second cladding region, the active structure having at least one quantum well. The VCSEL further includes a second mirror stack lattice matched to the second cladding region and having mirror pairs in a Al.sub.x Ga.sub.1-x As/Al.sub.y Ga.sub.1-y As material system. The second mirror stack including an etched region, thereby defining an annular emission region through which light generated by the annular waveguide VCSEL is emitted.
