Optoelectronics is the study and application of electronic devices that emit or detect light. These devices include light-emitting diodes (LEDs), lasers, photodetectors, and optical fibers. Optoelectronic devices are used in a variety of applications, including communications, lighting, and sensing.
Some of the emerging trends in optoelectronics include the development of flexible and transparent electronics, the use of nanomaterials for optoelectronic devices, and the use of organic light-emitting diodes (OLEDs) for lighting and display applications.
