Control of Frequency Combs with Passive Resonators

open access: yesSensors, 2023
Tailored optical frequency combs are generated by nesting passive etalons within mode-locked oscillators. In this work, the oscillator generates a comb of 6.8 GHz with 106 MHz side-bands.

Controllable Kerr and Raman-Kerr frequency combs in functionalized microsphere resonators

open access: yesNanophotonics, 2019
Optical frequency comb (OFC) based on the whispering-gallery-mode microresonator has various potential applications in fundamental and applied areas. Once the solid microresonator is fabricated, its structure parameters are generally unchanged. Therefore,

Towards generation of optical frequency comb in the short-wavelength visible region using periodically poled lithium niobate waveguides

open access: yesResults in Optics, 2021
We demonstrate the spectral broadening of an octave-spanning erbium-based frequency comb in two types of periodically poled lithium niobate (PPLN) waveguides.

Microresonator frequency comb optical clock

open access: yesOptica, 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

open access: yesAdvanced 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.
