Femtosecond laser written optical waveguide amplifier in phospho-tellurite glass

Opt Express. 2010 Sep 13;18(19):20289-97. doi: 10.1364/OE.18.020289.

Abstract

We report on the first demonstration of an optical waveguide amplifier in phospho-tellurite glass providing net gain at 1.5 μm. The device was fabricated using a high repetition rate femtosecond laser and exhibited internal gain across 100-nm bandwidth covering the entire C + L telecom bands.
