Optoelektroniset refers to the field of study and technology that deals with the interaction between light and electronic systems. This interdisciplinary area combines principles from optics, electronics, and materials science. Optoelectronic devices are designed to either emit light in response to an electric current, or to respond to incident light by changing their electrical characteristics.

Key components within optoelectronics include light-emitting diodes (LEDs), lasers, photodetectors, and photovoltaic cells. LEDs convert electrical energy into light, commonly used in displays, lighting, and indicators. Lasers, another form of light emitters, produce coherent and monochromatic light, finding applications in telecommunications, medical procedures, and industrial manufacturing. Photodetectors, such as photodiodes and phototransistors, convert light signals into electrical signals, essential for light sensing, optical communication receivers, and imaging systems. Photovoltaic cells, or solar cells, convert light energy directly into electricity, forming the basis of solar power generation.

The development of optoelectronics has been driven by advances in semiconductor materials, particularly compound semiconductors like gallium arsenide (GaAs) and indium phosphide (InP), which exhibit suitable electronic and optical properties. The applications of optoelectronic technologies are vast and continue to expand, impacting areas such as high-speed data transmission, consumer electronics, medical diagnostics, renewable energy, and industrial automation. The miniaturization and increased efficiency of optoelectronic devices are crucial for the progression of many modern technologies.
