To understand how light propagates through a medium we need to know the basics of electromagnetic theory, polarization, reflection, diffraction and diffraction. In this chapter we shall address the principles of reflection, refraction and diffraction

Light, like all its counterparts across the electromagnetic spectrum, has a wave-particle duality, that is, it has the properties of a wave and a particle, and the particles we call photons. It suits us when we are considering the subject of communic

Unless we are using a heliograph or smoke signals then we need to produce light for our optical communication system. By using electronic methods this means spontaneous or stimulated emission of a photon when an electron drops to a lower energy orbit

In testing optical systems there are generally four parameters of interest: attenuation of the link, its return loss, the continuity and polarity of the optical links and the length of the link. Other parameters of interest, such as bandwidth, cannot

Optical communications can be divided into Line of Sight, LOS, systems, and guided light methods. In this chapter we shall consider guiding light through silica-based optical fibres which represents by far the majority of optical communications syste

To understand better how light is used in modern optical communications, it helps to first understand the history of light and how people have used it throughout history to observe, send, and receive information. This chapter discusses early uses of

We have encountered many of the components of optical communications in earlier chapters. In Chapter 3 we encountered Faraday isolators; in Chapter 4 diffraction gratings which are used in wavelength division multiplexing devices, in Chapter 5 GRIN a

To make use of optical fibre communications channels we must encode useful information onto an optical carrier and successfully decode it at the receiving end. This can be done in either an analog or digital format although digital codes now represen
