Abstract :
We simulate an arbitrary chirp waveform generator to explore the fiber transmission performance of the output of chirp-inducing devices. Various chirp regimes are considered to find the optimum chirp profile for a post-compensated fiber link. If a chirp profile has a peak on the signal edges, ±5 ps/nm residual dispersion on a 40 Gb/s RZ signal results in ∼2 dB higher power penalty compared to a chirp peak located at the center of the pulse. With higher launch power, a single chirp peak on leading or trailing edge achieves ∼2 dB lower minimum power penalty (at 10−9 BER) compared to the profile with a chirp peak at pulse center.
