Effect of Temperature on the Dispersion Properties of Water-Filled Photonic Crystal Fibers

This study aimed to dynamically control the optical dispersion properties of water-filled photonic crystal fibers (PCFs) by adjusting their temperature and the wavelength of the applied pulse (0.8–1.5) nm. Using numerical modeling (finite element method), the effect of hole diameter (1.5–4.5 μm) and temperature (15–95 °C) on the zero-dispersion wavelength (ZDW) was analyzed. The results showed that increasing the hole diameter reduced the ZDW from 1.1324 to 1.0216 μm (at 15 °C) and increased the
