Abstract
We study the theoretical limits of optical communication channels affected by chromatic dispersion. By using as a metric the energy transfer ratio, we find the optimal transmitted pulse shape that allows the impact of dispersion to be minimized. We show that these optimized pulses perform significantly better than standard nonreturn-to-zero/on-off keying (NRZ-OOK) modulation.
