Photonics concerns the generation, transmission, manipulation, and interactions of light and its applications in many varied areas in research, industry, and everyday life. This general overview of photonics draws special attention to the development of laser sources, semiconductor optics, fiber optics, and photonic techniques such as ultrafast pulse generation. The wide range of applications is reviewed with particular attention to information technology and optical communications, optical information storage, displays, sensors, and industrial applications. The rapidly growing field of applications in biophotonics and biomedical optics is also emphasized with new techniques of optical coherence tomography (OCT) and optical trapping.
