Optoelectronics is a branch of technology that deals with the generation, detection, and control of light. It combines electronics and optics, allowing for devices such as laser diode controllers, fiber optic systems, and sensors to be created. Optoelectronics applications span from defense and security systems to communications. They can be used for navigation and monitoring, as well as for a variety of industrial processes. In addition, optoelectronics is used to create light sources that can be used for medical applications. Optoelectronics are also used in consumer products such as DVD players and digital cameras.
