Spirals of light may lead to better electronics

(Phys.org) —A group of researchers at the California Institute of Technology (Caltech) has created the optical equivalent of a tuning fork—a device that can help steady the electrical currents needed to power high-end ...

Photons a la Mode: Studying light pulses by counting photons

(Phys.org) —The photodetectors in Alan Migdall's lab often see no light at all, and that's a good thing since he and his JQI colleagues perform physics experiments that require very little light, the better to study subtle ...

Microelectronics: Automating cancer detection

Microelectronic engineers in Singapore have developed and tested sensor technology that can detect and measure a chemical signature of bladder cancer. The light-based sensor could eventually be used for the early diagnosis ...

NIST shows how to make a compact frequency comb in minutes

Laser frequency combs-high-precision tools for measuring different colors of light in an ever-growing range of applications such as advanced atomic clocks, medical diagnostics and astronomy-are not only getting smaller but ...
