What is optoelectronics?

The term optoelectronics was coined in the 1950s by British physicist Herbert Kroemer. He used the term to describe the combination of optical and electronic elements in a device or system. The term optoelectronics encompasses all methods and techniques that enable the conversion of electronically generated data and energy into light emission and vice versa. Light serves as a signal carrier for the transmission of information, for the measurement of physical quantities or for the generation of images.

Optoelectronics is based on the properties of light and photons and has its origin in phototechnology, which deals with the generation and use of light. Light is electromagnetic radiation that travels at the speed of light from one place to another. The properties of light, such as wavelength and intensity, can be used to transmit information. Photons are the elementary particles that make up light.

Optoelectronic Components

Optoelectronic components can be divided into actuators (transmitters) and detectors (receivers). Optoelectronic actuators are semiconductor components that generate light from electricity, such as lasers and light-emitting diodes. The emission of light can be located in both the visible and invisible spectral range (UV or infrared). Optoelectronic detectors are the counterparts to actuators and include, for example, photoresistors, photodiodes, and phototransistors. There are also light sensors that are constructed as integrated circuits, such as CCD sensors.

Optoelectronic components can also be divided into active and passive components. Active components emit electromagnetic radiation in the visible or invisible range and include LED lights, infrared sensors, UV emitters, and laser diodes. Passive components, on the other hand, process visible and invisible light, but do not generate radiation themselves. Passive components include, for example, infrared ray receivers, phototransistors, and photodiodes.

Optoelectronic Sensors

Optoelectronic sensors are devices that use light as a measure to gather certain information about the environment. They consist of an optoelectronic actuator that emits light and an optoelectronic detector that detects and measures the emitted light. When the actuator and detector are operated as a system, an optical sensor, also called an optosensor, is created.

Optoelectronic sensors are used in many fields, such as industrial automation, medical technology, traffic technology, and even consumer electronics. They can be used to measure distances, speeds, tilt angles, accelerations, and many other quantities. There are different types of optoelectronic sensors that are suitable for different applications. For example, there are fiber-optic sensors that guide light in glass fibers and are used for data transmission or distance measurement. There are also photodiode sensors that detect light and are used for measuring light intensities or detecting movements.

Materials in Optoelectronics

Materials in optoelectronics play an important role in the development of devices and components that serve as an interface between electrical and optical components or contain such components. An important property of materials in optoelectronics is their ability to emit or detect light. Semiconductor materials are usually used for this purpose because of their electrical properties.

Popular semiconductor materials for optoelectronic components include:

  • Semiconductor materials such as silicon and gallium arsenide
  • Glass fibers for optical data transmission
  • Polymer materials for flexible electronic devices
  • Quartz for optical components and semiconductor lasers
  • Sapphire for optical components and LED housing
  • Germanium for infrared detectors
  • Aluminum oxide for optical components
  • Zinc selenide for infrared detector
  • Barium sulfide for optical components
  • Indium phosphide for optical components and optical waveguides

However, this is just a selection of materials used in optoelectronics. The choice of material depends on various factors such as the desired property of the component (e.g. emission spectrum or detection sensitivity), the application to be solved, and the manufacturing method. Material selection is therefore an important part of the development of optoelectronic components and devices.

Optoelectronic applications

Optoelectronics is used in many areas, including:

» Optical communication and data transmission

use light to transmit information over long distances. They are used, for example, in fiber optic cables, laser printers, and projectors.

» Optical sensors and measuring systems

use light to measure physical quantities such as temperature, pressure, humidity, and movement. They are used, for example, in industry, medical technology, and environmental monitoring.

» Optical storage and data storage

use light to record and play back digital data. They are used, for example, in CD and DVD players, Blu-ray players, and hard drives.

» Optical image processing and image sensors

use light to generate and process images. They are used, for example, in cameras, smartphones, and drones.

» Optical display technology and lighting

use light to generate images and illuminate rooms and objects. They are used, for example, in monitors, televisions, projectors, and LED lamps.
