This project aims to explore novel approaches to leapfrog the capacity limit of a conventional single-mode fibre using concept of few-mode transmission. The proposed research entails few-mode fibre design, few-mode channel modelling, few-mode transmission simulation and digital signal processing for few-mode transmitter and receiver. The successful execution of the project can potentially bring about breakthrough technologies that could find applications in a wide range of places from optical interconnect to long-haul back-bone networks.
