摘要：
A high-order dispersion compensator (400) having a first order and a second-order polarization mode dispersion compensation elements including a polarization beam splitter (462) coupled to receive the polarization controlled signal and split it into a first polarization component and a second orthogonal polarization component. A first waveguide (472) having a first non-linearly chirped grating (474) receives the first polarization signal. A second waveguide (482) having a second non-linearly chirped grating (484) receives the second polarization signal. A first tuning (490) mechanism tunes both the first and the second grating simultaneously and a second tuning mechanism (492) tunes the second grating independently. The compensator also may have a static chromatic dispersion compensation element.
