Active waveguides written by femtosecond laser irradiation in an erbium-doped phospho-tellurite glass

Opt Express. 2008 Sep 15;16(19):15198-205. doi: 10.1364/oe.16.015198.

Abstract

We report on fs-laser micromachining of active waveguides in a new erbium-doped phospho-tellurite glass by means of a compact cavity-dumped Yb-based writing system. The spectroscopic properties of the glass were investigated, and the fs-laser written waveguides were characterized in terms of passive as well as active performance. In particular, internal gain was demonstrated in the whole C+L band of optical communications (1530- 1610 nm).
