Whispering Gallery Mode Resonator (WhiGaMoR) - now relocated to New Zealand!

The acronym "WhiGaMoR" is our tool!
Whispering Gallery Mode Resonators trap light in a "round" dielectric via Total Internal Reflection. Such optical resonators are known to possess ultra high quality factors, limited only by material absorption and surface roughness (and for very small resonators by radiative losses). We fabricate and study such Whispering Gallery Mode (WGM) Resonators made out of crystalline materials to either study extremely low loss cavities for frequency standards or highly non-linear χ2 crystals for extremely efficient non-linear optics. We organized the very successful 492. WE-Heraeus Seminar on "Micro & macro-cavities in classical and non-classical light". Recently we joint forces with Frank Vollmer to organize another WE-Heraeus Seminar 560. on "Taking Detection to the Limit: Biosensing with Whispering Gallery Mode resonators".

Besides experimental studies we work on highly efficient numerical tools for coupled WGM resonators and more generally deformed resonators. Furthermore we study the general interaction of light at dielectric interfaces, for example the Goos Hänchen Shift.



Please note that my group moved in 2015 with me to the University of Otago in Dunedin, New Zealand
