Nanowire Lasers Emit at Useful Wavelengths
MUNICH, Dec. 6, 2013 — Threadlike semiconductors can be made to emit light at useful wavelengths, demonstrating potential as lasers for applications in computing, communications, and environmental and biological sensing. Scientists at Technical University Munich (TUM) demonstrated laser action in the semiconductor nanowires at room temperature, which they say could work with silicon chips, optical fibers and even living cells. "Nanowire lasers could represent the next step in the development of smaller, fast...
