Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency ...

Mengxi Tan is at the School of Electronic and Information Engineering, Beihang University, Beijing 100191, China, and at the Integrated Photonics and Applications Centre (InPAC), RMIT University, ...

A new technical paper titled “High-efficiency and broadband on-chip electro-optic frequency comb generators” was published by researchers at Harvard, Stanford, Caltech, and Hyperlight. The research ...

The ultrabroadband infrared frequency comb could be used for chemical detection in portable spectrometers or high-resolution remote sensors. (Nanowerk News) Optical frequency combs are specially ...

The search for rocky, Earth-like exoplanets has received a boost, with the arrival of a new laser frequency comb at the European Southern Observatory’s La Silla Observatory in Chile. Built by a team ...

Unlike the jumble of frequencies produced by the light that surrounds us in daily life, each frequency of light in a specialized light source known as a "soliton" frequency comb oscillates in unison, ...

High-frequency combs have made possible some of the most advanced benchtop instrumentation available today (see for example, “Nonlinear VNA goes to 67 GHz,” edn ...

Researchers developed a new type of spectral shaper that can shape the spectrum of 10,000 lines of light from a laser frequency comb. The image shows the spatial light modulator they used with a 2D ...

Since the first demonstration of the laser in the 1960s, laser spectroscopy has become an essential tool for studying the detailed structures and dynamics of atoms and molecules. Advances in laser ...
