Nonlinear Transmission Modeling for UWB Optical Systems


One way to overcome the capacity limitations in the established optical network infrastructure is to extend the optical transmission bandwidth beyond the conventionally used C+L band. In contrast to the modeling of narrow band systems, it is crucial for ultra-wideband (UWB) transmission systems to consider inter-channel stimulated Raman scattering (ISRS).

The student's task is to understand the nonlinear process of SRS and describe possible modeling approaches for UWB optical systems.
