Optoelectronics is a branch of electronics that focuses on the study and application of devices that can interact with light. This field involves the development of electronic devices that can both emit and detect light, such as light-emitting diodes (LEDs), photodetectors, solar cells, and lasers. Optoelectronics plays a crucial role in various technologies, including telecommunications, medical devices, consumer electronics, and renewable energy systems. Researchers in this field work to improve the efficiency, performance, and applications of optoelectronic devices through the study of materials, device design, and fabrication techniques.
