Research Abstract

A continuous-wave (cw) Raman comb that provides an equally-separated narrow-line frequency components at a frequency of larger than 10 THz was demonstrated. It is based on a "continuous-wave molecular-optic modulator" that is a newly-developed method to control a lightwave. In order to characterize the cw Raman comb, a method to measure a phase-relationship between comb lines by combining an interferometric autocorrelator and optical heterodyne detector was developed. This allows us to quantify a phase difference of the cw Raman comb modulated at a frequency of 17.6 THz.
