When was optoelectronics invented?
The real history of optoelectronic devices began with the discovery of producing visible (red) light LEDs using the alloy semiconductor, GaAsP, in 1962 [2]. In the same year coherent near-infrared radiation around 840 nm has been observed from forward-biased GaAs p-n junctions [3].
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.
These are NOT interchangeable terms/concepts. If this is still confusing to you, if not even more confusing, I came up with a simple rule of thumb: If the device involves a semiconductor PN junction (as in any electronic devices), it's Optoelectronics; Otherwise, it's Electro-Optics.
Optoelectronic devices are used in a wide variety of application areas, such as optical fiber communications, laser technology, and all kinds of optical metrology. Optoelectronics is largely based on semiconductor materials.
Ultra-high-speed light pulses have made possible optical analysers for ultra-high-speed electronic circuits and electronic analysers for ultra-high-speed optical signals. An important area for opto-electronics in defence system is seeking or homing head for missiles, rockets and different kinds of ammunitions.
It's safe to say that optoelectronics aren't going to fade away anytime soon. Both industrial and academic communities predict a promising future for research in optoelectronics technology and advancements in both optics and photonics are expected to revolutionise the 21st century.
Light Emitting diode (LED): an optoelectronic device that emits non-coherent optical radiation at a photon energy close to bandgap of the junction.
1 Optoelectronics. Optoelectronic devices are light-emitting or light-detecting devices, either producing light or using light in their operation. Photodetectors, light-emitting diodes (LEDs) and laser diodes, optical amplifiers and optical modulators are some examples of optoelectronic devices.
Optoelectronic engineers design and develop optoelectronic systems and devices, such as UV sensors, photodiodes, and LEDs. Optoelectronic engineering combines optical engineering with electronic engineering in the design of these systems and devices.
As adjectives the difference between photoelectric and optoelectronic. is that photoelectric is of or relating to the electric effects of electromagnetic radiation, especially the ejection of an electron from a surface by a photon while optoelectronic is of or pertaining to optoelectronics.
Why do we need photonics instead of electronics?
However, combining electrical devices with integrated photonics provides a more energy efficient way to increase the speed and capacity of data networks, reduce costs and meet an increasingly diverse range of needs across various industries.

The two optoelectronic devices: - Photodiode and solar cell, have the same working principle but differ in terms of their process of operation.
Is LCD an optoelectronic device?
liquid crystal display (LCD), Optoelectronic device used in displays for watches, calculators, notebook computers, and other electronic devices. Current passed through specific portions of the liquid crystal solution causes the crystals to align, blocking the passage of light.
LED light comes from spontaneous emission, whereas laser diode light arises from stimulated emission. Thus, LEDs generally have lower output powers and omnidirectional emission. LEDs are efficient and small like their laser counterparts but typically operate at lower drive currents and are less expensive.
GPS and Geographic Information
Image processing systems rely on photonics and optical technology to refine data provided by global positioning systems (GPS).
Unlike the majority of electronic devices, which are silicon based, optoelectronic devices are predominantly made using III–V semiconductor compounds such as GaAs, InP, GaN and GaSb and their alloys due to their direct band gap.
Photovoltaic devices which convert optical radiation into electricity (solar cells).
