Photodetection and Measurement - Maximizing Performance in Optical Systems

Аннотация

The junction photodiode that is the focus of this book has been described in detail in many other books and publications. Here only a few basics are given, so that you can use the photodiode effectively in real circuits. A simple model is presented that allows the main characteristics and limitations of real components to be understood. The ability to correctly derive the polarity of a photodiode’s output, guess at what level of output current to expect, and have a feel for how detection speed depends on the attached load is necessary. The model we begin with has little to do with the typical real component fabricated using modern processing techniques; it is a schematic silicon pnjunction diode.
