Abstract
The frequency responses of wavelength-selective optical components often
exhibit ripples in the amplitude and/or phase. These ripples can lead to signal
distortion and hence a degradation in system performance. The pulse distortion
induced by sinusoidal amplitude and phase response ripples is derived for
chirped and unchirped Gaussian pulses, and closed-form expressions 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 that the power penalty induced by these ripples depends on the chirp and
pulsewidth of the transmitted signal. The combined effect of the characteristics
of the transmitted signal and ripple parameters on system performance is discussed
in detail. It is shown that the dependence of the maximum power penalty on
the chirp parameter differs for amplitude and phase response ripples. The
results of the theoretical analysis are in good agreement with numerical simulations.
