摘要：

In this letter, we propose and experimentally demonstrate a simple, passive, and self-referencing wavelength shift detection scheme for use in fiber Bragg grating sensing systems. The demodulation system is based on the interference between two modes in a polarization maintaining fiber loop mirror. Although it involves the use of an interference technique, it is stable compared with other conventional interference demodulators.
