Optoelectronics

The term optoelectronics is a specific discipline of electronics that focuses on light-emitting or light-detecting devices. Light-emitting devices use voltage and current to produce electromagnetic radiation  i.e., light. Such light-emitting devices are commonly used for purposes of illumination or as indicator lights. In contrast, light-detecting devices, such as phototransistors, are designed to convert received electromagnetic energy into electric current or voltage. Light-detecting devices can be used for light sensing and communication. Examples of these include darkness-activated switches and remote controls. In general terms, light-detecting devices work by using photons to liberate bound electrons within semiconductor materials.
