Your library or personal account may give you access

Abstract

Enabled by a dual-comb fiber laser, real-time interrogation of fiber Bragg grating’s spectral response is realized using the dual-comb spectroscopy scheme. kHz sampling speed and pm accuracy are simultaneously achieved with a simple fiber-optic setup.
