Dynamic dispersion compensation in a 10-Gb/s optical system using a novel voltage tuned nonlinearly chirped fiber Bragg grating

We experimentally demonstrate dynamic dispersion compensation using a novel nonlinearly chirped fiber Bragg grating in a 10-Gb/s system, A single piez oelectric transducer continuously tunes the induced dispersion from 300 to 1000 ps/nm, The system achieves a bit-error rate = 10(-9) after both 50 and 104 km of single-mode fiber by dynamically tuning the dispersion of the gr ating between 500 and 1000 ps/nm, respectively. The power penalty after 104 km is reduced from 3.5 to <1 dB.
