Estimation of Optical Filter Narrowing in High Speed WDM Systems
In this paper we demonstrate performance of three different optical filter transfer functions: Lorentzian, Raised Cosine and Supergaussian, and their influence on non return to zero (NRZ) coded optical signals in wavelength division multiplexing (WDM ...
