Raising the operating temperature of infrared detectors has benefits in terms of reduced cooler power and increased life and enables an overall reduction in size and weight for handheld applications. With MCT the composition can be tuned to achieve t

A low-cost high-radiance Ga 1− x Al x As/GaAs LED has been developed using p-n junction isolation to achieve current confinement in an inverted Burrus LED structure. Junction isolation avoids the use of proton implantation techniques leading to a s
