New nanolaser achieves high efficiency
Japanese scientists have developed a highly efficient,
room-temperature nanolaser that produces stable, continuous streams
of near-infrared laser light.
Yokohama National University researcher Toshihiko Baba and
colleagues said the overall device has a width of several microns,
while the part of the device that actually produces laser light has
dimensions at the nanometer scale in all directions.
The laser uses only 1 microwatt of power, achieving one of the
smallest operating powers ever reported.
The researchers said their nanolaser design should be useful in
miniaturized circuits containing optical devices.
The research appears in the journal Optics Express.
