- NaF) (ZBLAN) microfiber in the mid-infrared (mid-IR) regime have been investigated numerically. The results show that ZBLAN microfiber has large normal dispersion for wavelength ranging from 2 to 5 μm by tailoring the fiber geometry. Moreover, the Tm-doped mode-locked fiber laser has been modeled with the ZBLAN microfiber as the dispersion compensator, and the ultrafast pulse around 2 μm can be generated. The results confirmed the availability of the dispersion compensator for mid-IR ultrafast photonics.
