Spectrum controlled supercontinuum generation in microstructure tellurite fibers

Abstract

We report what we believe to be the first demonstration of flattened supercontinuum (SC) generation from a microstructure tellurite fiber pumped by a tunable ultrafast laser source with a pulse width of 180 fs. When the pump light is launched into 0.574 m long air-cladding tellurite fiber with small size air holes, which are comparable with the core diameter, we obtain flattened SC spectra expanding from 1000 to 2100 nm by tuning the pumping wavelength to the range of 1400-1600 nm. © 2009 The Ceramic Society of Japan.
