Abstract :
A novel scheme for quantitative calibration of a phase-shift formed in a linearly chirped fiber Bragg grating is numerically and experimentally demonstrated, which is based on the utilization of either a wavelength- or a power-interrogated fiber ring laser. Moreover, an application example of the proposed phase-shift FBG to temperature measurement has been proposed and experimentally demonstrated.
