Optoelectronics: Materials and Devices

Optoelectronics deals with the study and application of light-emitting or light-detecting devices. It is a distinct field of electronics. Optoelectronic devices include those that emit, channel, detect, or are controlled by light. The devices which emit light use voltage and current to produce electromagnetic radiation which is visible as light. Such light-emitting devices are commonly used for illumination or as indicator lights. Devices which are designed to convert electromagnetic energy...
