Description
Summary:The numerical model of CW-DFB optical source for fiber-optic transmission systems employing coherent detection technique is presented. The developed model is based on numerical solution of quantum-mechanical coupled rate equations. The numerical model is suitable for optical transmission systems for purpose of generation of optical carrier wave on the transmitter side as well as it can be used as local laser for coherent detection on the receiver side. The main attention of proposed optical source model is focused on signal, time-dependent characteristics to determine spectral properties of presented laser, which fully satisfies current requirements on coherent optical transmission systems. The efficiency of numerical model is also discussed. We have showed that by employing the re-sampling technique, both computational effort and accuracy of presented laser model are markedly enhanced.
