Paper Abstract

A novel temperature sensor based on injection fiber Bragg grating laser with wavelength and temporal domain demodulation is proposed and demonstrated experimentally. The proof of concept device consists of a DFB laser modulated by a RF signal as injection light, a fiber Bragg grating laser, an optical spectrum analyzer, and a digital oscilloscope. The dynamic range of the proposed sensor is explored. The results demonstrate the new concept of temperature sensors and the technical feasibility for temperature measurement.
