Experimental Researches on Birefringence of Fiber Bragg Grating
光纤光栅双折射效应的实验研究

The birefringence effects on uniform fiber Bragg grating (FBG) and linearly chirped FBG under lateral compression was experimentally investigated, respectively. The birefringence on uniform and linearly chirped FBG induced by pressure of piezoelectric ceramic (PZT). The induced birefringence of the FBG can be accurately controlled through tuning the voltage applied on PZT. Polarization mode dispersion (PMD) can be compensated using linearly chirped FBG.
