Influence of temperature on the optical properties of near-rectangle core photonic crystal fiber

Considering the variations of the refractive index and hole pitch with the temperature synchronously, the influences of temperature on the optical properties of near-rectangle core photonic crystal fibers (PCFs), especially on the polarization and dispersion, are analyzed with a full vector model based on super-lattice. Numerical results demonstrate that the variation of polarization and dispersion is quite little even if large variation in temperature occurs. This means that the near-rectangle core PCF has good temperature stability.
