We measured and calculated the spectral dependence of the polarimetric sensitivity to temperature (dB/dT) in a photonic crystal holey fiber. The birefringence in this fiber is induced by the elliptical shape of the core, which consists of a triple defect in the hexagonal structure. Comparison of the temperature sensitivity measured for the bare fiber and for the fiber with polymer coating shows that the stress induced by the thermal expansion of the polymer contributes significantly to the overall temperature response. Measurements carried out for the bare fiber demonstrate that the temperature sensitivity has a positive sign and strongly increases vs. wavelength. Additionally, we present the results of calculations of the spectral dependence of dB/dT obtained using a finite element method. The calculated and measured values of dB/dT show relatively good agreement.
