Abstract

Abstract

We demonstrate Al rich AlGaN based APDs grown on AlN substrates capable of high sensitivity at room temperature with ambient lighting rejection showcasing the advantage over Si and Ge based detectors. APDs are operated in linear gain region with maximum gain exceeding 1100.

Abstract

Abstract

A study of the well-width impact on the AlGaN laser is presented. The laser threshold and optical gain are significantly influenced by the quantum well design. A low threshold of 5 kw/cm2 is achieved in the 3 nm well width due to a reduced QCSE.

Abstract

Abstract

The development of near UV-laser diodes is presented. This includes growth of relaxed Ga-rich AlGaN layers as well as discussion of the electrical and optical properties of the devices. With the demonstration of optically pumped lasers a pathway toward electrically injected lasing is shown.
