Optoelectronics
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.[1]
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
- photovoltaiceffect, used in:
- photodiodes (including solar cells)
- phototransistors
- photomultipliers
- optoisolators
- integrated optical circuit(IOC) elements
- Photoconductivity, used in:
- photoresistors
- photoconductive camera tubes
- charge-coupled imaging devices
- Stimulated emission, used in:
- injection laser diodes
- quantum cascade lasers
- Lossev effect, or radiative recombination, used in:
- light-emitting diodes or LED
- OLEDs
- Photoemissivity, used in
Important applications[3] of optoelectronics include:
- Optocoupler
- communications
