In this work, we study a special kind of photonic crystal fibers with two integrated electrodes. The device operation is based on induced birefringence caused by mechanical stress when electrical current heats the internal electrodes. Due to the complex structure of the fiber, a finite element model was carried out to determine the strain distributions generated at the center region of the fiber core, and hence taking the induced change in the refractive index as a change in the effective refractive index due to the transferred heat. Here, we explain the interesting result that fiber birefringence axes rotated asymptotically with temperature. The analysis shows that this rotation of the birefringence axes is the cause of a nonlinear variation of the effective refractive index of the fundamental mode.
