Optoelectronics (oroptronics) is the study and application ofelectronic devices and systems that find, detect and controllight, usually considered a sub-field ofphotonics. In this context,light often includes invisible forms of radiation such asgamma rays,X-rays,ultraviolet andinfrared, in addition to visible light. Optoelectronic devices are electrical-to-optical or optical-to-electricaltransducers, or instruments that use such devices in their operation.[1]
Electro-optics is often erroneously used as a synonym, but is a wider branch ofphysics that concerns all interactions between light andelectric fields, regardless of whether they form part of an electronic device.
Optoelectronics is based on thequantum mechanical effects oflight on electronic materials, especiallysemiconductors, sometimes in the presence ofelectric fields.[2]
