Bj. Eggleton et al., Tunable dispersion compensation in a 160-Gb/s TDM system by a voltage controlled chirped fiber Bragg grating, IEEE PHOTON, 12(8), 2000, pp. 1022-1024
We demonstrate for the first time a device that enables practical dispersio
n management of a 160-Gb/s time-division multiplexedr system (return-to-zer
o duty cycle: 30%). The dynamic dispersion is provided by an integrated chi
rp-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.
