Coherent Perfect Absorption in Chaotic Optical Microresonators for Efficient Modal Control
Xuefeng Jiang, Shixiong Yin, Huanan Li +5
Non-Hermitian wave engineering has attracted a surge of interest in photonics in recent years. One of the prominent phenomena is coherent perfect absorption (CPA), in which the ann…
Distance between exceptional points and diabolic points and its implication for the response strength of non-Hermitian systems
Jan Wiersig
Exceptional points are non-Hermitian degeneracies in open quantum and wave systems at which not only eigenenergies but also the corresponding eigenstates coalesce. This is in stron…
Corrected perturbation theory for transverse-electric whispering-gallery modes in deformed microdisks
Manuel Badel, Jan Wiersig
The perturbation theory by L. Ge et al. [Phys. Rev. A 87, 023833] for transverse-electric polarized modes in weakly deformed microdisks omits terms related to the variation of the…
Superthermal photon bunching in terms of simple probability distributions
T. Lettau, H. A. M. Leymann, B. Melcher +1
We analyze the second-order photon autocorrelation function with respect to the photon probability distribution and discuss the generic features of a distribution that re…
Nonhermitian transport effects in coupled-resonator optical waveguides
Henning Schomerus, Jan Wiersig
Coupled-resonator optical waveguides (CROWs) are known to have interesting and useful dispersion properties. Here, we study the transport in these waveguides in the general case wh…
Rotating optical microcavities with broken chiral symmetry
Raktim Sarma, Li Ge, Jan Wiersig +1
We demonstrate in open microcavities with broken chiral symmetry, quasi-degenerate pairs of co-propagating modes in a non-rotating cavity evolve to counter-propagating modes with r…
Nonlinear dynamical tunneling of optical whispering gallery modes in the presence of a Kerr nonlinearity
Jeong-Bo Shim, Peter Schlagheck, Martina Hentschel +1
The effect of a Kerr nonlinearity on dynamical tunneling is studied, using coupled whispering gallery modes in an optical microcavity. The model system that we have chosen is the '…
Multimode Coupling by Boundary Wave Scattering
Li Ge, Qinghai Song, Brandon Redding +3
We show that coupling among multiple resonances can be conveniently introduced and controlled by boundary wave scattering. We demonstrate this principle in optical microcavities of…
Local chirality of optical waves in ultrasmall resonators
Brandon Redding, Li Ge, Qinghai Song +3
The local chiral symmetry between clockwise (CW) and counter-clockwise (CCW) propagating light in a deformed microcavity can be broken by wave optics effects, which become signific…
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) […
Measurement of the Goos-Hänchen shift in a microwave cavity
Julia Unterhinninghofen, Ulrich Kuhl, Jan Wiersig +2
We present measurements of the Goos-Hänchen shift in a two-dimensional dielectric microwave cavity. Microwave beams are generated by a suitable superposition of the spherical waves…
Electromagnetic modes in cavities made of negative-index metamaterials
Jan Wiersig, Julia Unterhinninghofen, Henning Schomerus +2
We discuss electromagnetic modes in cavities formed by metamaterials with negative refraction and demonstrate that the straightforward approach to substitute negative values of the…
Ray-wave correspondence in limacon-shaped semiconductor microcavities
Susumu Shinohara, Martina Hentschel, Jan Wiersig +2
The limacon-shaped semiconductor microcavity is a ray-chaotic cavity sustaining low-loss modes with mostly unidirectional emission patterns. Investigating these modes systematicall…
Quality factors and dynamical tunneling in annular microcavities
Arnd Bäcker, Roland Ketzmerick, Steffen Löck +2
The key characteristic of an optical mode in a microcavity is its quality factor describing the optical losses. The numerical computation of this quantity can be very demanding for…
Lifetime statistics in chaotic dielectric microresonators
Henning Schomerus, Jan Wiersig, Jörg Main
We discuss the statistical properties of lifetimes of electromagnetic eigenmodes in dielectric microresonators with fully chaotic ray dynamics. Using the example of a resonator of…
Asymmetric scattering and non-orthogonal mode patterns in optical micro-spirals
Jan Wiersig, Sang Wook Kim, Martina Hentschel
Quasi-bound states in an open system do in general not form an orthogonal and complete basis. It is, however, expected that the non-orthogonality is weak in the case of well-confin…
Formation of long-lived, scarlike modes near avoided resonance crossings in optical microcavities
Jan Wiersig
We study the formation of long-lived states near avoided resonance crossings in open systems. For three different optical microcavities (rectangle, ellipse, and semi-stadium) we pr…
Opto-mechanical probes of resonances in amplifying microresonators
Henning Schomerus, Jan Wiersig, Martina Hentschel
We investigate whether the force and torque exerted by light pressure on an irregularly shaped dielectric resonator allow to detect resonant frequencies, delivering information com…
Hexagonal dielectric resonators and microcrystal lasers
Jan Wiersig
We study long-lived resonances (lowest-loss modes) in hexagonally shaped dielectric resonators in order to gain insight into the physics of a class of microcrystal lasers. Numerica…

Jan Wiersig
A boundary element method based on a Green's function technique is introduced to compute resonances with intermediate lifetimes in quasi-two-dimensional dielectric cavities. It can…
