Silicon Photonic Integrated Circuits for Reconfigurable Optical Add/Drop Multiplexer in Multicore Fibre Communication

Project Details


The information revolution has modified our life style in terms of work, services, medical treatment, entertainment, etc. Nowadays, optical fibre networks are capable of transmitting a large amount of information by means of short pulses of light. It has been thought that the transmission capacity of optical fibres would be inexhaustible. However, the fast increasing demands from HDTV, IPTV, rich media services, as well as business services are pushing the amount of information transmitted over traditional optical fibre networks close to their ultimate capacity limitation. Multicore fibre communication, where multiple cores are introduced in a single fibre, exploits space as a new dimension, allowing a many-fold increase of capacity. However, achieving a higher transmission capacity is only one requirement for future networks. In order to achieve a real commercial success, this new technology must also support photonic routing in future multicore fibre network nodes, where many functionalities still remain to be demonstrated. This project will explore integrated solutions for the required functionalities in multicore fibre communication, targeting low loss and low energy consumption of network nodes. The project will develop a compact silicon chip integrating all the networking functionalities together, aiming to demonstrate a powerful module and pushing multicore fibre communications one step closer to reality.
