The main goal of the group is to develop wave guide based components, which can generate or manipulate light.
In one of our projects, we utilize liquid crystals placed in microscopic channels around the wave guide core, to filtrate light or change its polarization properties. The properties can be cóntrolled with temperature or electrical fields, which produces very flexible and compact components.
Another project focusses on utilizing the optical linearity of the wave guide, which makes it possible for different light signals to affect eachother. This can be used in transmitting optical energy from one wave length to another, thus strengthening a data signal with pulsating light at another wavelength.
Finally, we are working on building lasers with different wave guides, that can send out strong light pulses shorter than a trillionth of a second. These lasers will be more robust and cheaper than today's lasers, which will make them available to many uses within medicin and materials processing.
