Brief Handbook Description: Optical telecommunications has revolutionized the way we receive information and communicate with one another. Driven by the ever-increasing internet, data, video and voice communication requirements, it has played a major role in ushering in the Information Age. Optical fibre has unprecedented capabilities for transmitting data at Tbit/s rates and beyond. This is important for diverse applications including long-distance trunk communications, metropolitan local area networks, and the distribution of multi-channel video television signals in the customer access network. Fibre systems are also central to national broadband distribution networks for delivering high speed data, video and information services. The foundations for these widespread applications are based on the advantages of fibre communications, namely that the signal is guided in an excellent medium and that the signalling rates can be very high. The enormous bandwidth of optical communication systems drives the worldwide deployment of lightwave systems for data, internet, multimedia and voice services.

This course will provide an understanding of the fundamental principles of optical fibre communication systems. It presents optical fibre propagation characteristics and transmission properties. Then it describes light sources and the fundamental principles of laser action in semiconductor and other lasers including quantum well lasers, tunable lasers and fibre lasers, as well as the characteristics of optical transmitters based on semiconductor and electro-optic modulation techniques. The characteristics of optical amplifiers are also discussed. On the receiver side, the principles of photodetection and optical receiver sensitivity are presented. Other aspects such as fibre devices and multiple wavelength division multiplexing techniques are also discussed. Finally, the design of complete optical fibre communication systems is presented for data transmission, optical networks, and multi-channel systems.
Assumed Knowledge: (ELEC3405 OR ELEC9405) AND (ELEC3505 OR ELEC9505). Basic knowledge of communications, electronics and photonics
