Paper Abstract

We report a novel device that the reflected intensity of Bragg grating (FBG) inscribed in a polarization-maintaing fewmode fiber (PM-FMF) is tuned by temperature from 56°C to 156°C with a wavelength shift of 1nm and intensity decrease of ~10dBm. The reflection spectrum and corresponding mode coupling are analyzed, the calcultated birefringence B for LPo1, LP11a and LP11b polarized modes are 4.3×10-4 , 4.6×10-4 and 4.7×10-4 , respectively, which agree with the specified birefringence of the PM-FMF, B ~5.0×10-4 .
