Abstract
Vertical cavity surface emitting lasers (VCSELs) seem to have a lot of applications due to their many unique advantages including single longitudinal optical mode operation, surface normal output, ease of fabrication into two dimensional arrays and wafer level testing. The paper discusses the performance of a InGaAs/AlGaAs based IR VCSELs employing continuous grading schemes in the DBRs and efficient room temperature CW operation of VCSELs at red (670 nm) wavelengths using AlGaInP/AlGaAs heterostructures in the optical cavity. Also discussed is the advantage of MOVPE for the growth of vertical cavity surface emitting laser diodes.
