The increase of the information transmission capacity using wavelength division multiplexing (WDM) transmission systems requires low cost compact amplifiers for metro use. Er-doped planar waveguide amplifiers are thus envisaged.
We are currently investigating a novel erbium-doped oxide glass based on Bi2O3, which exhibits broadband emission and negligible concentration quenching up to 13,000 ppm of Er concentration.
In this study, we report the fabrication of channel waveguides in a Bi2O3-based glass. Erbium doped channel waveguides were fabricated using direct laser writing (with a UV beam at 244 nm) into a bulk Er-doped glass.
The fabrication technique and results will be presented. The mode profile, loss, change in refractive index will be reported.
