Doped polymeric optical waveguide amplifiers

摘要

A polymer-based optical waveguide amplifier comprises a polymer host material doped with rare earth ions wherein the polymer host material is a material that functions as a resist in a direct patterning technique. The polymer host material can be epoxy novalac resin doped with Er³⁺ ions and Yb³⁺ ions, and the direct patterning comprises electron beam direct writing or UV printing.
