Current research in Optics and Photonics
The research includes three main areas: (1) Technology and component structures within integrated photonics and nanophotonics, with generic applications towards telecommunications, interconnect, sensors, lighting, energy and medicine. (2) Optical high-capacity transmission and (3) optical networks, where the first area is a base for the latter two. The research involves a mixture of applied and comparatively basic fundamental research, the former represented by, e.g., optical networks, and the latter by, e.g., the photonic properties of nanoparticle.
Quantum Electronics and Quantum Optics
Basic research on the fundamental properties of light, interaction between light and matter, and quantum mechanical information transfer (such as quantum cryptography) and quantum information processing. Generation and detection of single photon pulses and the application of these. Research on photons entanglement and its applications.
Fundamental research on the interaction between light and matter, in the form of atoms, molecules and solids. The laser used in nonlinear spectroscopy and the study of time-dependent quantum phenomena. Principles of laser physics and quantum effects when the laser acts as oscillator and amplifiers. The long-term goal is that part of the research results generated will have practical impact, i.e., to develop technology and materials for more efficient and better light sources.
Research is primarily conducted in two areas: (1) Electromagnetic optics and (2) spectroscopy in semiconductors. In both these areas the emphasis is on near-field optics and includes research on diffractive optics, micro-lasers, Raman lasers, plasmonics, ultrafast processes in semiconductors and their nanostructures.
