The main learning objective is to treat the design and operating characteristics of advanced digital optical fibre communication systems. Students will obtain an understanding of the dynamical behaviour of laser diodes; principles of optical modulation; characteristics of optical fibre waveguides and optical receivers. In addition students will gain an appreciation of the role of these components in determining the performance of practical optical communications systems.

• Direct current modulation of laser diodes; laser rate equations and their solution; limitations to direct current modulation; external modulation. • Mechanisms for optical switching and routing; candidate structures • Light propagation in optical fibres; fibre losses and dispersion; transmission windows • High impedance and trans-impedance receivers; optical amplifiers and repeaters • Modulation Formats. Modulator Technologies. Coherent Optical Communications Systems. System Design
