The quest for orange and yellow lasers

Compound Semiconductor Magazine features "Quantum well intermixing: The quest for orange and yellow lasers"

"The LED light bulb is destined to consign incandescents and fluorescents to the history books. That’s because this lighting source has much to recommend it – it is efficient, long lasting, and hits full brightness in an instant – and its sales are accelerating as prices plummet."

"But the LED might not have the final say in the rise of solid-state lighting. In time, it could be superseded by white-light sources formed by mixing the output of diode lasers emitting at different wavelengths. Attractions of this laser-based technology are the promise of even higher efficacies, a superior colour quality and light-based communication rates that are an order of magnitude higher than those that could be produced by LEDs."
