ABSTRACT:
An optical waveguide for use in amplifying light signals with an integrated gain equalization filter. The optical waveguide includes a gain section for amplifying light signals. The optical waveguide further includes an equalization filter to improve the uniformity of optical gain over a wavelength range for which the gain section is intended to provide amplification.
