Basics and Theory

摘要: Optical absorption is a fundamental process which exploited when optical energy converted into electrical energy. Optoelectronic receivers are based on this conversion process. Photodetectors convert In chapter, the most important factors needed for comprehension of photodetectors will be summarized in compact form. For detailed description basics absorption, book [1] can recommended. Here, emphasis will, course, placed silicon devices. After collection and optoelectronic definitions, we summarize fundamentals device physics modeling solid-state electron devices including A review found [2]. semiconductor equations with implemented photogeneration models carrier mobility used simulators listed first. Carrier drift diffusion as well their consequences speed quantum efficiency explained. Furthermore, equivalent circuit photodiode discussed order to show further aspects concerning photoreceivers.
