Abstract :
We demonstrate the generation of a 1.1-1.7μm supercontinuum in a 1.3m long air-suspended- core tellurite holey-fiber with a nominal zero-dispersion wavelength of ~1.38μm. The fiber is pumped at 1.06μm with a 20ps pulsed fiber laser. The high Raman gain-coefficient of tellurite glass is attributed a key role in the supercontinuum generation.
