Scottish scientists reduce speed of light in free space


Although the speed of light can be slowed slightly as it travels through materials such as water or glass, it was until now thought impossible for photons to be slowed as they travel through free space.

Optofluidic sensor irradiated with light measures blood sugar noninvasively


An optofluidic sensor that, when irradiated with light, can measure glucose (blood sugar) level through the skin without drawing blood.

Coherent combination of multiple CW semiconductor lasers produces arbitrarily shaped optical pulses

Coherent combination of multiple CW semiconductor lasers produces trains of arbitrarily shaped optical pulses

01/21/2015 By combining light generated at different wavelengths from different continuous-wave (CW) laser diodes, researchers at the University of Southampton (Southampton, England) can create trains of arbitrarily shaped optical pulses.

Handheld laser method could improve cancer surgery

01/21/2015 To help surgeons better detect malignant tissue during cancer surgery and hopefully reduce the rate of cancer recurrence, a team of scientists has developed a new imaging system that causes tumors to "light up" when a...
