Integrated dual optical frequency comb source

Optics Express, 2020
A monolithically integrated dual-channel optical frequency comb source is demonstrated in this paper. Three lasers are integrated on a single chip using a regrowth-free fabrication process in a master-slave-slave configuration. The master laser’s power is split equally using a 1x2 multimode interference coupler and injection locks the two slave lasers.

Microresonator frequency comb optical clock

Optica, 2014
Optical-frequency combs enable measurement precision at the 20th digit, and accuracy entirely commensurate with their reference oscillator. A new direction in experiments is the creation of ultracompact frequency combs by way of nonlinear parametric optics in microresonators.

Spectral Peaked Optical Frequency Comb for Highly Sensitive Spectroscopy

Advanced Photonics Research
Optical frequency combs represent a breakthrough in the field of metrology. Because an optical frequency comb has a large number of comb modes, the optical energy is dispersed over the comb modes, and the optical energy per comb mode is very small.

Raman-Kerr comb generation based on parametric wave mixing in strongly driven Raman molecular gas medium

Physical Review Research, 2020
We report on experimental and theoretical demonstrations of an optical comb spectrum based on a combination of cascaded stimulated Raman scattering and four-wave mixing mediated by Raman-induced nonresonant Kerr-type nonlinearity.
