Electrically Tunable Power Efficient Dispersion Compensating Fiber Bragg Gratings for Dynamic Operation

We demonstrate a power efficient (0.5W) tunable dispersion compensating fiber bragg grating device and show for the first time dynamic optimization of dispersion in a nonlinear lightwave system. Operation is demonstrated in a 20 Gbit/s single channel NRZ system where the device was used to adjust the dispersion to the power dependent optimal dispersion required for optimum performance.
