Optoelectronics is the study and application of electronic devices that interact with light. In this context, light often includes invisible forms of radiation such as ultraviolet and infrared. Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation.
Optoelectronics includes the following physical phenomena.
- Photoelectric or photovoltaic effect, used in:
- Photoconductivity, used in:
- Stimulated emission, used in:
- Lossev effect, or radiative recombination , used in:
- light-emitting diodes or LED
- Photoemissivity , used in
- photoemissive camera tube
Important applications of optoelectronics include:
Electro-optics is often erroneously used as a synonym, but is in fact a wider branch of physics that deals with all interactions between light and electric charge, whether or not they form part of an electronic device.
