Supplemental Task-High Power Lasers

Abstract

The researchers made significant progress in all of the proposed research areas. The first task involved the growth and characterization of 1040 nm vertical external cavity surface emitting lasers (VECSELs). These devices have been grown by MOCVD and have been subjected to temperature-dependent reflectivity studies to optimize the alignment of the gain peak with the micro-cavity as well as examining their continuous wave output power properties. Secondly, based on extensive electronic structure simulations, single and dual tunnel-injection based quantum dot epi-structures have been designed. These structures leverage from the already established world-class quantum dot VECSEL research at CHTM.
