SYSTEM FOR HIGHER-ORDER DISPERSION COMPENSATION INCLUDING A DELAY LINE

摘要

A high-order dispersion compensator having a first order and a second-order polarization mode dispersion compensation elements including a polarization beam splitter coupled to receive the polarization controlled signal and split it into a first polarization component and a second orthogonal polarization component. A first waveguide having a first non-linearly chirped grating receives the first polarization signal. A second waveguide having a second non-linearly chirped grating receives the second polarization signal. A first tuning mechanism tunes both the first and the second grating simultaneously and a second tuning mechanism tunes the second grating independently. The compensator also may have a static chromatic dispersion compensation element.
