Zero-dispersion-wavelength-decreasing tellurite microstructured fiber for wide and flattened supercontinuum generation.
We report wide and flattened supercontinuum generation in zero-dispersion-wavelength-decreasing tellurite microstructured fibers fabricated by using the tapering method. Flattened supercontinuum light expanding from 600to2800 nm can be generated when launching a 1550 nm femtosecond fiber laser into a 5-cm-long, zero-dispersion-decreasing, tellurite microstructured fiber. Our results show that short length (several centimeter) zero-dispersion-wavelength decreasing highly nonlinear fiber has a potential for generating wide and flattened supercontinuum light sources.
