After 29 years at the University of Southampton -- six of those as deputy director of it Optoelectronics Research Centre (ORC) -- retiring professor David Hanna gave a valedictory talk during a ceremony held Friday at the university. Hanna joined the university in October 1963 as a research student in the electronics department, was promoted to professor of physics in 1988 and was named deputy director of the Optoelectronics Research Centre in 1989. He has made pioneering contributions in the areas of nonlinear optics and laser physics; his work has made advances in nonlinear optical...Read full article

    nonlinear optics
    Nonlinear optics is a branch of optics that studies the optical phenomena that occur when intense light interacts with a material and induces nonlinear responses. In contrast to linear optics, where the response of a material is directly proportional to the intensity of the incident light, nonlinear optics involves optical effects that are not linearly dependent on the input light intensity. These nonlinear effects become significant at high light intensities, such as those produced by...
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
