Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the ...

By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in ...

Using two optical frequency combs and a photon counter, the experiments open up exciting prospects for conducting dual-comb spectroscopy in low-light conditions and they pave the way for novel ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have discovered a new way to generate ultra-precise, evenly spaced "combs" of laser light on a ...

TOKYO--(BUSINESS WIRE)--Sevensix Inc. (Headquarters: Minato-ku, Tokyo; CEO: Yosuke Hane) is pleased to announce the full-scale launch of its proprietary optical frequency comb generator, Frush, in the ...

By harnessing two natural timescales in resonator arrays, researchers created photonic chips that reliably produce multiple harmonics without active compensation. For decades, scientists and engineers ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...
