In this work, we demonstrate a novel high-power vertical-cavity surface-emitting laser (VCSEL) array with highly single-mode (SM) and single-polarized output performance without significantly increasing the intra-cavity loss and threshold current ( I

In this paper, we demonstrate a novel structure for 850- and 940-nm wavelength high-speed vertical-cavity surface-emitting lasers (VCSELs). Extra shallow apertures (~20 nm) are etched on the topmost current spreading (CS) layer of 850- or 940-nm VCSE

The functionality of novel parallel and series high-speed vertical-cavity surface-emitting laser (VCSEL) arrays, which can greatly relax the tradeoff between output power and modulation speed, is demonstrated. Both types of array structure allow impr

By using p-type modulation doping in the highly strained MQWs of high-speed 850 nm VCSELs, significant enhancements in speed, slope efficiency, and maximum power have been simultaneously achieved as compared to those of un-doped references.
