Membrane Reflector Vertical Cavity Lasers at Near- and Midwave-Infrared

摘要

We carried out both fundamental and developmental research on a novel DBR-free membrane reflector based VCSELs (MR-VCSELs), with the demonstration of 1550 nm lasing operation at room temperature. The laser consists of an InGaAsP QW based heterostructure, sandwiched in between two single-layer photonic crystal Fano resonance silicon nanomembrane reflectors. Detailed theoretical and experimental work has been carried out towards high performance single layer broadband membrane reflector demonstrations, MR-VCSEL cavity design, and optically pumped laser demonstration at room temperature. The thermally engineering membrane reflectors have also been investigated for high performance lasers.
