INDUSTRY NEWS
Laser scanning comes to Mount Rushmore
While laser scanning has been popularized by various TV shows in forensic applications, it can also be used to create virtual 3-D maps of world heritage sites.
Cree bucks economic downturn with record quarterly earnings
LED lighting company Cree announced record revenue of $148.1 million for its fourth quarter (Q4) of fiscal 2009, which represents a 9% increase compared to the same quarter last year.
JDSU mid-year loss widens, but looking up in 2010
Optical components manufacturer JDSU reported net revenue for its fiscal Q4 of $276.1 million and the net loss was $59.5 million, or $0.28 per share.
 
BLOG: Larry’s VC View on entrepreneurs and failure
"I was recently confronted by someone who cited the “failure” of one of my past companies as evidence that I don’t know how to run a business, and it kind of shocked me, but I thought it might make a fun blog:"

TECHNOLOGY NEWS
Suntech achieves record multi-crystalline PV efficiency
Suntech Power Holdings, manufacturer of photovoltaic (PV) modules, achieved a new world record conversion efficiency of 15.6% on a commercial grade multi-crystalline silicon PV module.
Cornell quantum dots make world's tiniest nanolaser
Researchers have modified nanoparticles known as "Cornell dots" to make the world's tiniest laser--so small it could be incorporated into microchips to serve as a light source for photonic circuits.
Nuclear-fusion research is key to EUV lithography method
Researchers at Purdue University are adapting methods used in fusion-energy research to create extremely thin plasma beams for a new class of nanolithography.

Targeted pulse-energy routing in fiber drives nonsupercontinuum applications
While routing femtosecond pulse energy to a broadband spectrum in optical fibers is important, many emerging nonsupercontinuum applications require selective routing of the pulse energy to an isolated spectral band by exploiting certain properties of the optical fiber itself.
Single-mode fiber has very low bending loss
Scientists at the Gwangju Institute of Science and Technology have created a single-mode fiber that has a bending loss of only 0.014 dB/loop at 1550 nm for a bending radius of 5 mm.
Chirped PC fibers break pulse-duration limits in femtosecond beam delivery
Chirped photonic-crystal fibers offer new possibilities for guiding sub-100 femtosecond light pulses without compromising pulse duration and peak power.
Fluorine-doped core boosts radiation resistance of single-mode fiber
Reliable fiber-optic communications in high-radiation environments such as linear accelerators and nuclear reactors is made possible by silica fibers with optimized fluorine-doped cores.
