Title:

SILICATE WAVEGUIDE COMPOSITIONS FOR EXTENDED L-BAND AND S-BAND AMPLIFICATION

Document Type and Number:

WIPO Patent Application WO2003057639

Kind Code:

A8

Abstract:

An optical waveguide including a core having silica, Al, a non-fluorescent rare-earth ion, Ge, Er, and Tm. The non-fluorescent rare-earth ion may be La. Exemplary compositions concentrations are Er is from 15 ppm to 3000 ppm, Al is from 0.5 mol% to 12 mol%, La is less than or equal to 2 mol%, Tm is from 15 ppm to 10,000 ppm; and the Ge is less than or equal to 15 mol%. The core may further include F. An exemplary concentration of F is less than or equal to 6 anion mol%.
