{{Short description|Branch of electronics involving optics}}{{Distinguish|electro-optics}}(File:Light sensor.png|thumb|Electronic light sensors)Optoelectronics (or optronics) is the study and application of electronic devices and systems that find, detect and control light, usually considered a sub-field of photonics. In this context, light often includes invisible forms of radiation such as gamma rays, X-rays, ultraviolet and infrared, in addition to visible light. Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation.BOOK,weblink Supramolecular Materials for Opto-Electronics, Smart Materials Series, November 20, 2014, 10.1039/9781782626947, 978-1-84973-826-2, pubs.rsc.org, Electro-optics is often erroneously used as a synonym, but is a wider branch of physics that concerns all interactions between light and electric fields, whether or not they form part of an electronic device.Optoelectronics is based on the quantum mechanical effects of light on electronic materials, especially semiconductors, sometimes in the presence of electric fields.WEB,weblinkweblink dead, Physics and Technology - Vishay Optoelectronics, May 16, 2016,
