Mode Exchange by Cyclic Parameter Variation in Dielectric Microcavity

Not Accessible

Your library or personal account may give you access

Abstract

We show that resonance modes in microcavities can be exchanged under a cyclic parameter variation in 2-D parameter surface. The mode exchange implies that the cyclic variation encircles a singular point, so-called exceptional point. We analyze the topological structure of eigenvalue planes near the singular point.
