Paper Abstract

Optical fiber temperature sensors can provide accurate temperature information and adapt to different temperature environments well, so they have been widely used. Traditional optical fiber temperature sensors depend upon optical fiber grating or nonlinear back scatting, both of which need complex measurement systems and high cost. So, a simple and chip temperature sensing method was put forward based on fiber delay technology, and the temperature information was obtained by measuring additional delay of optical signal in fiber. Establishing an experiment system by using the frequency domain phase method, we obtained the delay coefficient which describes the relationship between delay and temperature, so that the feasibility of the method was proved.
