Extract

There is a broad spectrum of electronic devices, e.g., high electron mobility, heterojunction bipolar (HBTs) and modulation doped field effect (MODFETs) transistors, and optoelectronic devices, e.g., low-threshold quantum-well (QW) lasers, which employ strained InyGa1-yAs layers to improve device performance due to the enhanced flexibility in the electronic structure. These devices have very promising applications. For example, the ultra-low threshold lasers are going to play a major role in computer interconnect circuits due to their low-power consumption. Strainlayer InGaAs/GaAs QW lasers are of considerable interest as a possible candidate for pumping the upper states of Er-doped silica fiber amplifiers of optical networks.
