Dr. Limberger has served as a member of different Technical Program Committees, e.g. Optical Fiber Communication Conference (OFC 2010-2013), European Conference on Optical Communications (ECOC 2009-2018), and Bragg Gratings, Photosensitivity, and Poling in Glass Waveguides (BGPP). He was a topical chair of ECOC 2011, 2016, and 2017. In 1999 he founded the summer school on Photosensitivity in Optical Waveguides and Glasses (POWAG). He organized and co-chaired the 15th International Laser Physics Workshop, LPHYS'2006 (EPFL, Switzerland) and he was part of different conference steering committees (ECOC, LPHYS, POWAG). Currently he is program chair of BGPP topical meeting which is part of the OSA Advanced Photonics Congress 2018 (Zürich, Switzerland).
The following research areas are currently covered:
Glass structural changes: Characterization of laser induced photosensitivity in germanium doped and germanium free silica optical fibers using grating writing and measurement of laser induced birefringence changes. Characterization of laser induced stress and inelastic strain changes.
Novel all fiber lasers: realization and characterization of bismuth doped silica optical fiber lasers with FBG as laser mirrors.
Optical fiber sensors: fiber gratings for extended nondestructive testing
Reliability of optical fibers and components: stability of UV-induced refractive index changes
Grating characterization tools: development of Optical Low Coherence Reflectometry systems (phase and amplitude); development of tomographic birefringence measurement systems.
