Researchers claim smallest semiconductor laser

From EETimes: Physicists at the University of Texas-Austin say they have developed the world's smallest semiconductor laser in collaboration with colleagues in Taiwan and China.

The researchers say the development is a breakthrough for emerging photonic technology with applications from computing to medicine.

"We have developed a nanolaser device that operates well below the 3-D diffraction limit," said Chih-Kang "Ken" Shih, professor of physics at the University
of Texas, in a statement. "We believe our research could have a large impact on nanoscale technologies."

Shih and his colleagues reported in this week's issue of the journal Science the first operation of a continuous-wave, low-threshold laser below the 3-D diffraction limit. When fired, the nanolaser emits a green light. The laser is too small to be visible to the naked eye.
