Optical fibres are extensively used today to transfer information over long distances due to their low loss and cost. They are therefore a fundamental part of the internet today. However, it is estimated that current fibre technologies will not be able to deal with the ever increasing demand for data. One of the technologies proposed to combat this are multimode fibres which would allow more information to be propagated through a single fibre. Yet these fibres will require systems that can convert information between optical modes.
In my talk I will introduce the multimode generalised nonlinear Schrödinger equation which is extensively used in simulating pulse propagation in optical fibres. Furthermore, I will highlight the numerical method used in solving this equation and present a case study where it was successfully utilised. Finally, I will discuss the potential future applications for the model and some possible flaws.
Bio: I am an iPhD student at the Centre of doctoral training in Next Generation Computational modelling. My research entails simulating mode propagation through optical fibres. In particular I am interested in the nonlinear effects and their potential applications in multimode optical fibre systems.
