Abstract

Multijunction VCSELs with up to eight active regions are fabricated with integrated surface relief features for transverse mode suppression. Using this approach, we demonstrate a single mode 940nm VCSEL with a record high power of 14.2 and SMSR >30dB during room temperature, continuous wave operation.
