Abstract
Wavelength-selective optical components used in WDM optical communication systems often exhibit a transfer function with amplitude and phase ripples. These ripples can lead to signal distortion and performance degradation. The pulse distortion induced by sinusoidal amplitude and phase response ripples is derived for Gaussian pulses, and concise results are presented for the power penalty in system performance. The analysis shows that the amplitude and phase response ripples have a similar impact on the transmitted signal, and the power penalty induced by these ripples depends on the chirp and pulse width of the transmitted signal. The combined effect of the characteristics of the transmitted signal and the ripple parameters on the system performance is discussed in detail. Numerical simulations show a good agreement with the theoretical analysis.
