Welcome to the website of the PCF Emeritus Group

Please note that the Division has become a small emeritus group at the end of March 2021, following the statutory retirement of Philip Russell. As a result the group is no longer recruiting PhD students, but can still offer Masters projects. Enquiries about postdoctoral positions are also welcome, although the opportunities are limited. In either case, please send an email, with your curriculum vitae and a statement of your research interests, to Bettina Schwender at Bettina.Schwender@mpl.mpg.de.


The Division of Photonic Crystal Fibre Science is part of the  Max-Planck Institute for the Science of Light, founded in January 2009. It was formerly part of a Max Planck Research Group at the Friedrich-Alexander-University of Erlangen-Nuremberg. The Division has over 40 members (laboratory assistants, masters and doctorate students, post-doctoral researchers and visitors) from all over the world. There is a strongly international atmosphere, and as a result the working language is English (though many of us speak German).


For all general inquiries, please contact Bettina Schwender at:

The Max Planck Institute is located right next to the Science Campus of the Friedrich-Alexander-University Erlangen-Nuremberg, on its northern edge. See the information page on how to find us.

The Division works on scientific applications of photonic crystal and microstructured fibres. Photonic crystal fibre was first proposed by Philip Russell in 1991, and his group reported the first example of a working PCF in 1996. Since that time many groups all over the world have become active in developing PCF and exploiting its many applications. In the division we are carrying out a wide range of experiments that make use of the remarkable properties of PCFs. These include ultrafast nonlinear dynamics in gas-filled hollow-core PCF, optomechanical effects in nano-scale glass structures, orbital angular momentum in twisted PCF and laser propulsion and manipulation of particles in hollow-core PCF.
