摘要：

A modified Sagnac interferometer-based fiber temperature sensor is proposed. Polarization-independent operation and high temperature sensitivity of this class of sensors make them-cost effective instruments for temperature measurements. A comparison of the proposed sensor with Bragg grating and long-period grating fiber sensors is derived. A temperature-induced spectral displacement of 0.99 nm/K is demonstrated for an internal stress birefringent fiber-based Sagnac interferometer. (C) 1997 American Institute of Physics.
