Mode Tuning in Microresonators Using Uniaxial Anisotropy and Resonator Shaping — •Stefan Declair, Cedrik Meier, Torsten Meier, and Jens Förstner — University of Paderborn, Department of Physics and CeOPP, Warburger Str. 100, D-33098 Paderborn, Germany

We numerically investigate resonant modes in microdisks and photonic crystal cavities. Mode tuning of the resonant modes, which is desirable for many applications, e.g. for achieving strong coupling, in a broad frequency range is shown using (a) uniaxial anisotropy of either the surrounding environment or the photonic structure and (b) in non-cylindrical microdisks. In both cases anticrossing behavior is observed when modes of different mode order approach each other. Additionally, we compare our simulations with experimental results from a 3 µm microdisk embedded in a liquid crystal environment.
