For high-speed and large-capacity optical communication applications and improvement of accuracy in microwave generation and evaluation equipment Results: NTT and their partners have developed a ...

Researchers from the University of Rochester and CalTech say they have created the first microwave-rate soliton microcomb that can control the repetition rate at a high speed. Microcombs are frequency ...

Optical frequency combs have revolutionized technologies such as atomic clocks, spectroscopy, and ultra-fast lasers by acting as precise bridges between optical and microwave frequencies. As the ...

How it works: the top frequency comb is passed through a sample of interest and then into a beamsplitter. The bottom frequency comb operates at a slightly different pulse repetition frequency and is ...

This study demonstrates a compact optical modulation platform that enables real-time, high-resolution spectroscopy using sub-MHz interleaved combs generated via chip-scale acousto-optic phase ...

NTT Corp. (NTT) and Tokyo Denki University, both based in Japan, have succeeded in further stabilizing the output of an optical frequency ruler generated by modulating the intensity and phase of laser ...

GOLDEN, Colo.--(BUSINESS WIRE)--Vescent Technologies announces the new RUBRIComb™ and RUBRIColor™ — a rugged, low-SWaP optical frequency comb and wavelength extensions covering 490 to 2000 nm with ...

Laser frequency combs are valuable analytical tools for observing chemical phenomena or detecting the presence of particular species at low concentrations. The key to these applications is the ...
