The science of photonics includes the generation, emission, transmission, modulation, signal processing, switching, amplification, detection and sensing of light. The term photonics basically covers all technical applications of light over the whole spectrum from ultraviolet over the visible to the near-, mid- and far-infrared. The term photonics developed as an outgrowth of the first practical semiconductor light emitters invented in the early 1960s and optical fibers developed in the 1970s.
Today at DTU Fotonik, we deal with the design, fabrication and characterization of new types of optical devices based on the newest developments in nanotechnology, such as sensors, lasers, LEDs, photovoltaic elements and devices for all-optical signal processing. Novel structures for applications in future quantum information technologies are also being explored. We investigate and demonstrate new techniques for ultra-high speed optical transmission systems and networks for distributing high-speed data to end-users. We optimize network layout and administration, and develop efficient data compression codes that enhance the quality and minimize the resources needed.
