A high-performing room-temperature nanolaser

Abstract:
Scientists at Yokohama National University in Japan have built a highly efficient room-temperature nanometer-scale laser that produces stable, continuous streams of near-infrared laser light. The overall device has a width of several microns (millionths of a meter), while the part of the device that actually produces laser light has dimensions at the nanometer scale in all directions. The laser uses only a microwatt of power, one of the smallest operating powers ever achieved. This nanolaser design should be useful in future miniaturized circuits containing optical devices. The researchers present their nanolaser in the latest issue of Optics Express, an open-access journal published by the Optical Society of America ("Room temperature continuous wave operation and controlled spontaneous emission in ultrasmall photonic crystal nanolaser").
