Temperature Dependence Of Microbend-Induced Birefringence In Optical Fibers

Abstract

The temperature dependence behaviour of the microbend-induced birefringences of single mode fibers has been experimentally investigated. It is found that the temperature dependence of the microbend-induced birefringence of an elliptically jacketed fiber is much smaller than that of a non-polarization preserving fiber. In agreement with the theory, measurements show that the temperature dependence of the birefringence can be interpreted using the photoelestic effect of the fiber, and the corresponding stress on the fiber due to the microbending can be deduced from the experimental data.
