Laser frequency combs may be the future of Wi-Fi

Wi-Fi and cellular data traffic are increasing exponentially but, unless the capacity of wireless links can be increased, all that traffic is bound to lead to unacceptable bottlenecks.

Team shows tiny frequency combs are reliable measurement tools

In an advance that could shrink many measurement technologies, scientists at the National Institute of Standards and Technology (NIST) and partners have demonstrated the first miniaturized devices that can generate desired ...

Optical distance measurement at record-high speed

Microresonator-based optical frequency combs enable highly-precise optical distance ranging at a rate of 100 million measurements per second – publication in Science: Scientists of Karlsruhe Institute of Technology (KIT) ...

Celebrated optical trick goes vibrational

A micromechanical device generates a series of precise, equally spaced vibration frequencies, analogous to the light of the "optical frequency comb," which has dramatically improved precision measurements and could lead to ...

Frequency combs—on-chip integration on track

EPFL scientists have found a way to miniaturize frequency combs, realizing a new step toward miniaturization of such tools. Their device can measure light oscillations with a precision of 12 digits.

Optical clock technology tested in space for first time

For the first time, an optical clock has traveled to space, surviving harsh rocket launch conditions and successfully operating under the microgravity that would be experienced on a satellite. This demonstration brings optical ...

Team takes giant step forward in generating optical qubits

An optical chip developed at INRS by Prof. Roberto Morandotti's team overcomes a number of obstacles in the development of quantum computers, which are expected to revolutionize information processing. An international research ...
