The proposed VCSEL consists of a 1550 nm active cavity having top and bottom DBR mirror systems sitting on top of a 980 nm electrically pumped intracavity VCSEL structure made up of a 980 nm active MQW
cavity with top and bottom GaAs/[Al.sub.0.8][Ga.sub.0.2]As DBR mirror systems and grown on a GaAs substrate.
A high-intensity emission peaked at around 447 nm is from the InGaN/GaN MQW
lasers exhibit transfer functions from RF to light, which generally offer good linearity, but adequate dynamic range for applications in cellular and cordless systems requires further improvement in this linearity parameter.
The multiple quantum well (MQW
) layer is simplified as the interface between the two GaN layers, and the effect of the backside reflector is taken into account by applying their reflectance spectra as the surface property of the backside of sapphire substrate.
However, in conventional planar epilayers, the InGaN/GaN multiple quantum well (MQW
) contains large strain, which would induce a high dislocation density and piezoelectric field, due to the mismatches in lattice constant and thermal expansion between heteroepitaxial layers.
The LED structure consisted of a low-temperature 200 nm thick GaN buffer layer, a 2 [micro]m thick undoped GaN layer, a 2 [micro]m thick and highly conductive n-type GaN layer, an InGaN-GaN multiple-quantum-well (MQW
) active layer, and a 0.5 [micro]m thick p-type GaN layer.
