Photoinduced Second-Harmonic Generation (SHG) in Ce- and Eu-doped aluminosilicate glass fibers

Not Accessible

Your library or personal account may give you access

Abstract

The presence of defects in the glass is considered a key factor for the observation of photoinduced second-harmonic generation (SHG) in fibers1. Until now efficient SHG has been associated with Ge-doped fibers, i.e. Ge-defects. Here we report the first observation of efficient photoinduced SHG in rare-earth doped aluminosilicate fibers that do not contain Ge. Conversion efficiencies in such fibers exceed those observed in most Ge-doped fibers.
