Abstract

An experimental study is conducted to investigate temperature effects on the polarization characteristics of three polarization-maintaining (PM) fibers designed to operate in the 1.3 micrometers wavelength region. A conventional single-mode (SM) fiber is used for a comparison. The polarization stability of the test fibers is evaluated as a function of temperature (between -60 degree(s)C and 100 degree(s)C). Significant changes are observed in the extinction ratio at -60 degree(s)C for one of the PM fibers containing a UV-cured buffer coat. It is believed that lateral compressive forces due to the buffer coat shrinking onto a nonuniform glass fiber at low temperature cause microbending and mode coupling. While the test fibers containing the UV-cured buffer coats are in general more sensitive to temperature changes, some fiber designs seem to perform better according to the experimental results.
