SYSTEM FOR HIGHER-ORDER DISPERSION COMPENSATION INCLUDING PHASE MODULATION

摘要

A higher-order dispersion compensator (300) including a chromatic dispersion compensator (312) coupled to receive an input signal; a phase modulator (380) optically coupled to the chromatic dispersion compensator, wherein the phase modulator selectively chirps portions of the data pulses; and a tunable dynamic dispersion element coupled to receive the phase modulated signal. The tunable dynamic dispersion element includes a first waveguide (392) having a first non-linearly chirped grating (394) tuned to reflect the polarization controlled signal and having a first reference reflection point; and a first tuning mechanism that (396) tunes the first grating.
