Applications of unique slow light materials


The Swedish National Metrology Institute at RISE is looking for a committed and talented PhD student to be affiliated with the Division of Atomic Physics at the Faculty of Engineering (LTH), Lund University.
About the position
The Division of Atomic Physics at the Faculty of Engineering (LTH), Lund University, Sweden has a staff of over 50 researchers. The research at the division is mainly focused on lasers and optics, and with several topics, ranges from spectroscopy to quantum information. More information can be found at
This announced position will be linked to the quantum information group, which has a strong activity on quantum information and quantum optics using rare-earth-ion-doped crystals.
As a country, Sweden offers one of the best conditions in the world for Ph.D. students, including a yearly salary of about €34000 and a strong social security net.
Subject descriptions: Applications of unique slow light materials
Under special circumstances the speed of light can be slowed down dramatically. In rare-earth-ion doped crystals, the crystal acts as a natural trap for the rare-earth dopant ions. These crystals offer a unique solid state system, where light can be slowed down more than a factor 100 000. In this project, applications of these slow light materials will be explored. Recently we have demonstrated that slow light effects in Fabry-Pérot cavities made of rare-earth-ion-doped crystal materials can decrease cavity mode spacing and line widths by 3-5 orders of magnitude. Furthermore, we have shown that in such cavities the effect of length fluctuations on the cavity resonance frequency is decreased by 3-5 orders of magnitude compared to a conventional vacuum cavity of the same length. In this project the main aim is to investigate the potential of these results to improve the stability of lasers beyond what is currently possible.
