Description
Summary:A ZBLAN photonic crystal fiber (PCF) with normal dispersion is theoretically designed and investigated. The designed PCF can provide a large normal dispersion coefficient and a low confinement loss in a broad wavelength range of 1.8&#x2013;3.6&#x00A0;&#x03BC;m. Especially, the PCF exhibits an ultra large normal dispersion value of &#x2212;351.3&#x00A0;ps&#x002F;km&#x002F;nm and a small confinement loss of 0.05&#x00A0;dB&#x002F;m at 2.9&#x00A0;<italic>&#x03BC;</italic> m. By using the designed PCF as a dispersion compensator in a mode-locked ZBLAN fiber laser, stretched pulse with compressed pulse duration of 1.56&#x00A0;ps is numerically achieved.
