| Popis: | By employing the liquid crystal refractive index changes induced by applied electric field, a novel polarization rotator with low crosstalk and shorter length of rotation has been proposed and theoretically analyzed. The mode field distribution, birefringence of the fiber fundamental mode and the influence on birefringence of some parameters are simulated by full-vector finite element method. The results demonstrate that the polarization axis of the guided mode is determined by the rotation angle. When temperature is increased from 15 °C to 45 °C, the birefringence of tellurite photonic crystal fiber filled with liquid crystal gradually decreases. At the wavelength of 1.55 μm, the polarization angle of 45°, this kind of the polarization rotator have low crosstalk and shorter length of rotation. These distinguished features ensure its important applications in the integrated optical systems. |
