Liquid crystals for controlling polarization inside waveguides

The journal "Optical Materials Express" has just (04.03.2024) reported that a research group led by Dr Alberucci and Prof. Nolte has developed a new way of modulating optical signals in a laser-written waveguides in glass by inserting a liquid crystal layer.

The Institute of Applied Physics (IAP) at the Friedrich Schiller University Jena has a long-standing tradition and competence in design, fabrication and application of active and passive optical and photonic elements. It is also very well-known for its developments in the area of high power laser technology and nowadys also in quantum optics. Collaborative projects with companies ensure practical relevance and feasibility.
