All-fiber electro-optic dual optical frequency comb for fiber sensors

Abstract

We present a new technique for generating a Dual Optical Frequency Comb and we apply the technique on a Chirped Fiber Bragg Grating sensor to demonstrate quasi-static absorption measurements. In addition, it can be also applied to dispersion measurements. This technique is able to generate RF mapping of two optical frequency combs without the use of an acousto-optic modulator.
