The phenomenon of ultra-broadband optical spectrum that occurs when a high-power ultrashort pulse propagates through a nonlinear medium is known as supercontinuum (SC). It is difficult to extend the SC spectrum using silica fiber into the mid-infrared region. Therefore, research on SC generation in fluoride fibers that have high transparency in the mid-infrared region has been reported. Here, we report the results of numerical simulation of SC generation in ultrashort pulses with an incident center wavelength of 1.55 µm using a tapered fluoride fiber.
