We report what we believe to be the first demonstration of flat supercontinuum generation expanding from 1000 to 2100 nm from a microstructure tellurite fiber pumped by a tunable ultrafast laser source.
The optical emission characteristics of Bi-doped soda-lime-silicate glass is investigated in the near-infrared region. Results show an emission bandwidth FWHM as wide as 600 nm under 720 nm laser excitation. This is the widest emission bandwidth ever reported for bismuth-doped glass making it suitable for broadband amplifier and tunable laser applications.
