Glossary
light-emitting diode
An LED, or light emitting diode, is a semiconductor device that emits light when an electric current passes through it. LEDs are widely used in various applications due to their energy efficiency, compact size, and long operational life. The technology behind LEDs is based on the phenomenon of electroluminescence. Key characteristics and features of LEDs include: Electroluminescence: The process by which LEDs emit light is called electroluminescence. It involves the recombination of...
optoelectronics
Optoelectronics is a branch of electronics that focuses on the study and application of devices and systems that use light and its interactions with different materials. The term "optoelectronics" is a combination of "optics" and "electronics," reflecting the interdisciplinary nature of this field. Optoelectronic devices convert electrical signals into optical signals or vice versa, making them crucial in various technologies. Some key components and applications of optoelectronics include: ...
