Abstract :
We demonstrate for the first time a device that enables practical dispersion management of a 160-Gb/s time-division multiplexer system (return-to-zero duty cycle: 30%). The dynamic dispersion is provided by an integrated chirp-tunable Bragg grating which is capable of recovering 2-ps pulses over a tuning range of 50 ps/nm with system power penalty less than 1.3 dB.
