Keywords:Optical frequency comb, Dual-comb spectroscopy

Dual-comb spectroscopy is a powerful spectroscopic method that can measure broadband spectral information with high accuracy in a short acquisition time. We have been particularly developing a new method to evaluate the complex refractive index of solid samples based on the dual-comb technique. In this research, we aimed to realize a simple and practical dual-comb spectroscopic system with broad applicability to samples and measurement conditions by developing an all-fiber-typed dual-comb spectroscopic system, which is compact, stable, and easy to use.
