Optical Transmitters

  • Martin Sibley


Every optical link has a source of light in it. It may be a LED or a laser of some sort. With the exception of fibre lasers, a semiconductor diode generates the light. This chapter is concerned with the generation of light from LEDs and lasers. It begins with some semiconductor physics before going on to examine light generation from a variety of sources. Fibre lasers are also discussed.
