The group has both experimental and theoretical activity within nanophotonics and photonic components. The group is involved in interdisciplinary cooperation with other groups of the faculty, among others things through the projects SMIDA and nanolaser. There is also cooperation with other education institutions and with the industry. The activity includes among other things:
- Interferometry
- Fiberoptics – comunication and sensors
- Phase-modulation of coherent light
- Periodic structures within electromagnetism and optics.
- Acustooptics
- Negative refractive index and causality.
Laboratory facilities

The work is part of a project on modeling and fabrication of nanowires lasers. The nanowires are approximately 10-100 nm in diameter and a few micrometers long. In this work we model the electromagnetic and electric properties associated to such nanowires, to be able to optimize the geometry and structure of the nanowires with respect to performance. For more information, see the nanolaser project.

Speckle reduction techniques will be investigated in order to find a decent method to reduce speckle contrast in laser display systems. Both established and new techniques will be tested. A modulator will be built based on the most promising speckle reduction method.

Photonic crystals are materials with periodic variations in the refractive index. This may for example be a transparent material with holes in a uniform and periodic pattern. Such materials may for example be used as insulators for light, optical filters, and in various sensors. Work is currently in progress to build a set-up to create such photonic crystals using interferometric lithography. The initial focus will be to use the crystals to improve the coupling of light out from a light emitting diode (LED).
