Frequency combs are optical spectra composed of a set of discrete equally spaced lines.
Such spectra can be generated by diverse sources such as mode-locked lasers, resonators …

Optical frequency combs (OFCs) are a unique kind of light source, which are represented as
a series of equally spaced coherent spectral lines in the frequency domain. OFCs can …

Earth-like planets, dark energy and variability of fundamental physical constants can be
discovered by observing wavelength shifts in the optical spectra of astronomical objects …

Orbiting planets induce a weak radial velocity (RV) shift in the host star that provides a
powerful method of planet detection. Importantly, the RV technique provides information …

Continuous-wave laser-driven, high-Q Kerr–nonlinear optical microresonators have enabled
the generation of optical frequency combs, ultralow-noise microwaves and ultrashort optical …

The detection of satellites around extrasolar planets, so called exomoons, remains a largely
unexplored territory. In this work, we study the potential of detecting these elusive objects …

Micro‐optical frequency combs are miniaturized coherent light sources exhibiting a
tremendous influence on precision spectroscopy, optical clocks, and high‐speed optical …

Photonic technologies offer numerous functionalities that can be used to realize
