摘要：
A Vertical Cavity Surface Emitting Laser (VCSEL) is optimized for longer life of the VCSEL by controlling the distance of doped and undoped layers near an active region. In addition, the VCSEL optimized for reduced parasitic lateral current under an oxide of the VCSEL by forming a high Al confinement region and placing the oxide at a null in a standing optical wave. Further, the VCSEL is optimized to reduce resistance.
