Abstract

Suspended core microstructured optical fibers were fabricated of TeO2-WO3-La2O3 glass with reduced content of 3d-transition metals and hydroxyl groups impurities by drilled preforms stretching. Total loss in the best sample was less than 3 dB/m within 1-2 μm with minimum of 0.7 dB/m at 1.4 μm. The broadband emission with 1300 nm bandwidth was successfully generated in 0.8 m of TWL fiber using 2 nJ femtosecond laser as a source.
