Single Semiconductor Nanowire (IMAGE)
Caption
TUM researchers have demonstrated that semiconductor nanowires like the one shown here can act both as lasers, generating coherent pulses of light, and as waveguides, similar to optical fibers. Because these nanowire lasers emit light at technologically useful wavelengths, can be grown on silicon substrates, and operate at room temperature, they have potential for applications in computing, communications, and sensing.
