Optoelectronic devices are electronic components that combine optical and electronic functions. They can emit, detect, or manipulate light, making them essential in various applications. Common examples include LEDs (light-emitting diodes), photodetectors, and laser diodes. These devices are widely used in communication systems, lighting, and imaging technologies. The operation of optoelectronic devices relies on the interaction between light and electrical signals. When light is absorbed by a photodetector, it generates an electrical current, while LEDs convert electrical energy into light. This unique capability allows for advancements in fields such as telecommunications and medical imaging.
