Optoelectronics is a branch of technology that focuses on the interaction between light and electronic devices. It involves the study and application of materials that can emit, detect, and control light, such as semiconductors and lasers. Common applications include LEDs, solar cells, and fiber optic communication systems. This field combines principles from both optics and electronics, enabling the development of devices that can convert electrical signals into optical signals and vice versa. Optoelectronic components are essential in various industries, including telecommunications, medical devices, and consumer electronics, enhancing performance and efficiency in these technologies.
