(a) Schematic diagram of the pump burst and the Stokes burst in the time domain. N: number of pulses in burst. ∆τ: inter-pulse temporal separation. φ: pulse-to-pulse offset phase. Ω R: Raman frequency ...

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 ...

Application-driven development of microcombs. The arrows around the microcomb module indicate the relative importance of the power and number of comb lines for different applications, which include ...

The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a level of precision approaching the theoretical limit allowed by quantum ...

Key result A six-year-long research effort has seen researchers in Canada build a chip-scale device that can generate multiphoton entangled states. (Courtesy: Ultrafast Optical Processing Group) ...

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 ...

A frequency comb is a special kind of laser light whose spectrum, or set of frequencies, resembles the teeth of a comb. Instead of containing just one colour (one frequency), it emits a large number ...

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 ...
