- We present the first detailed numerical study of the impact of receiver low-pass filtering in soliton interaction-limited communication systems. We propagate 40-Gb/s pseudorandom bit sequences (PRBS's) of 28-1 solitons up to one soliton collision distance (Zc-) and optimize the filter bandwidth to minimize the interaction induced eye opening penalty. The distance at 0.5-dB penalty is increased over 40% through filtering. The penalty is essentially pulsewidth independent when considering distances normalized by Zc. We also show that PRBS's of at least 28 - 1 solitons are required to accurately simulate random data.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents a detailed investigation of how solitons broaden in the presence of polarization-mode dispersion (PMD). For a given degree of PMD and pulse width there exists an optimum choice of group-velocity dispersion, for which solitons are most resistant to the effects of PMD. We also optimize the soliton power enhancement factor and find that solitons can propagate roughly twice the distance compared to linear pulses in the absence of group-velocity dispersion. Finally we investigate the PMD robustness of dispersion managed solitons, and in the case simulated we find no quantitative difference as compared to conventional solitons.

Tidskriftsartikel (refereegranskat)abstract
- Since enhanced power solitons are usually applied in dispersion-managed soliton systems, it might be expected that dispersion-managed solitons have a stronger resistance to polarisation-mode dispersion than conventional solitons. However, it is shown that dispersion-managed solitons behave similarly to conventional solitons in terms of resistance to polarisation-mode dispersion.

- This letter presents a detailed investigation of how solitons broaden in the presence of polarization-mode dispersion. For a given amount of polarization-mode dispersion and pulsewidth there exists an optimal choice of group-velocity dispersion, for which solitons are most resistant to the effect of polarization-mode dispersion. We also optimize the soliton power enhancement factor and find that solitons can propagate roughly twice the distance compared to linear pulses in the absence of group-velocity dispersion.
