Analysis of multiple exceptional points related to three interacting eigenmodes in a non-Hermitian Hamiltonian
Jung-Wan Ryu, Soo-Young Lee, Sang Wook Kim
We have investigated the exceptional points (EPs) which are degeneracies of a non-Hermitian Hamiltonian, in the case that three modes are interacting with each other. Even though t…
Nonorthogonal pairs of copropagating optical modes in deformed microdisk cavities
Jan Wiersig, Alexander Eberspächer, Jeong-Bo Shim +4
Recently, it has been shown that spiral-shaped microdisk cavities support highly nonorthogonal pairs of copropagating modes with a preferred sense of rotation (spatial chirality) […
Quasiscarred modes and their branching behavior at an exceptional point
Jung-Wan Ryu, Soo-Young Lee
We study quasiscarring phenomenon and mode branching at an exceptional point (EP) in typically deformed microcavities. It is shown that quasiscarred (QS) modes are dominant in some…
Designing coupled microcavity lasers for high-Q modes with unidirectional light emission
Jung-Wan Ryu, Martina Hentschel
We design coupled optical microcavities and report directional light emission from high- modes for a broad range of refractive indices. The system consists of a circular cavity…
