Dielectric perturbations: anomalous resonance frequency shifts in optical resonators
Farhan Azeem, Luke S. Trainor, Patrick A. Devane +6
Small perturbations in the dielectric environment around a high quality whispering gallery mode resonator usually lead to a frequency shift of the resonator modes directly proporti…

Nonreciprocity in giant Goos-Hänchen shift due to symmetry breaking
Madhuri Kumari, S Dutta Gupta
We study giant Goos-Hänchen (GH) shift in reflection from a near-symmetric coupled waveguide structure. We show that broken spatial symmetry can lead to GH shift with different sig…
