The tapered tellurite microstructure optical fiber for the super-continuum generation

We demonstrate super-continuum (SC) generation in tapered tellurite microstructure optical fiber (MOF). The difference of SC generation is investigated by fabricating the tellurite MOF and tapered tellurite MOF at the same pumping condition. The length of tapered region is 3cm and the core diameter is from 7 μm to 4 μm. We get the optical bandwidth of the SC from 950 to >2400nm at the tapered MOF. In this paper, we systematically research the effect of tapered tellurite MOF on the SC generation.
