Abstract :
The power penalty due to the dispersion slope of WDM filters limits the number of cascaded filters and restricts the allowed signal-filter detuning. This dispersive penalty is significantly larger for optically-preamplified receivers. The results in this paper apply to systems with arbitrary bit rates. When dispersive penalties become a limitation, chirped Bragg filters with compensated dispersion slope or dispersionless waveguide-grating-router and Mach-Zehnder filters can be used
