Abstract

We report the simultaneous recovery of temperature and strain through measurement of polarization changes in the LP01 and LP11 modes of Andrew Corporation elliptical-core fiber. This technique required the development of an in-line mode splitter/analyzer, which is also described. The scheme has been demonstrated to be sensitive to changes of 1 °C and 5 μ∊ and is compatible with white-light multiplexing methods to provide quasi-distributed information.
