Dynamic gain slope compensator |
摘要 |
A dynamic slope compensation filter (DSCF) provides dynamic gain slope modification for an optical amplifier. The optical amplifier provides amplification for a plurality of wavelengths within an amplification band. The filter includes an optical waveguide core, an optical waveguide cladding and an optical waveguide overcladding. The optical waveguide core guides a plurality of wavelengths. The core has a core refractive index and includes at least one coupler that functions to couple at least a portion of the plurality of wavelengths from the core to the cladding. The optical waveguide cladding surrounds the core and has a cladding refractive index that is less than the core refractive index. The optical waveguide overcladding surrounds at least a portion of the cladding and has a variable overcladding refractive index that is adjustable within a range that is less than and greater than the cladding refractive index. At least one of a trailing edge and a leading edge of a filter loss peak of the filter covers substantially all of the amplification band.
