Photodiodes,ible to operate continuously over a wide range of temperatures for many years. A further obvious requirement for optical fibre links is that the detector size must be compatible with the fibre dimensions. This chapter examines PIN and APD structures for near and far infrared.

Introduction to Receiver Design,o coherent detection which is the preferred detection method in radio systems. (Long-haul optical links use coherent detection. These are examined when we consider current and future systems in the final chapter.) Although most of the work presented in this chapter is concerned with digital links, analogue receivers are also considered.
