Optical telecommunications has revolutionized the way we receive information and communicate with one another. It underpins broadband access networks, data centres, computer networks, and the next generation 5G. This course will provide an understanding of the fundamental principles of optical fibre communication systems. This includes optical fibre propagation characteristics and transmission properties. Then light sources are considered and the fundamental principles of laser action in semiconductor and other lasers, including nanotechnology for quantum well lasers, tunable lasers, optical amplifiers, and optical transmitters based on semiconductor and electro-optic modulation techniques. On the receiver side, photodetection principles, nanotechnology photodiode structures, and optical receiver sensitivity will be presented. Other aspects such as photonic integration, as well as multi-channel multiplexing techniques will also be discussed. Finally, the complete optical fibre communication system will be studied to realise high capacity digital transport for data centres, local area networks and multi-channel optical systems.
