- Abstract
Optical frequency combs are a unique tool for fundamental metrology, spectroscopy, and a broad spectrum of applications. High-Q microresonators serve as a promising platform for the generation of coherent frequency combs. The key characteristics that determine the properties of an optical frequency comb are the microresonator dispersion parameters. We have developed and verified an original technique that allows one to measure the dispersion coefficients with a high accuracy for both crystalline and integrated microresonators with the free spectral ranges from gigahertz to terahertz. We demonstrate the generation of a soliton optical frequency comb in an integrated microresonator pumped by a laser diode in the self-injection locking regime at a wavelength of 1.55 μm and show that its spectral characteristics closely correspond to the measured microresonator dispersion parameters.
