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) [ J. Wiersig et al. Phys. Rev. A 78 053809 (2008)]. Here, we provide numerical evidence which indicates that such pairs are a common feature of deformed microdisk cavities which lack mirror symmetries. In particular, we demonstrate that discontinuities of the cavity boundary such as the notch in the spiral cavity are… 

Frobenius–Perron eigenstates in deformed microdisk cavities: non-Hermitian physics and asymmetric backscattering in ray dynamics

In optical microdisk cavities with boundary deformations the backscattering between clockwise and counter-clockwise propagating waves is in general asymmetric. The striking consequence of this

Pair of Exceptional Points in a Microdisk Cavity under an Extremely Weak Deformation.

TLDR
It is demonstrated that such a degeneracy can appear in optical microdisk cavities by deforming the boundary extremely weakly, and it is shown that the exceptional points come in nearly degenerated pairs, originating from the different symmetry classes of modes.

The combination of high Q factor and chirality in twin cavities and microcavity chain

TLDR
This work demonstrates a novel, robust, and general mechanism to obtain the chirality in circular cavity by placing a circular cavity and a spiral cavity in proximity, and shows that ultra-high Q factor, large chiralities, and unidirectional output can be obtained simultaneously.

Non-Hermitian Effects Due to Asymmetric Backscattering of Light in Whispering-Gallery Microcavities

A whispering-gallery microcavity is an open optical system which supports well confined counterpropagating electromagnetic waves. Deforming the boundary of the cavity or perturbing it by other means,

Exceptional points in extraordinary optical transmission through dual subwavelength metallic gratings.

TLDR
It is shown that a classic analogue of exceptional points can be observed in the transmission spectra of dual subwavelength metallic gratings in complex metamaterials.

Quantum noise and mode nonorthogonality in non-Hermitian PT-symmetric optical resonators

PT-symmetric optical resonators combine absorbing regions with active, amplifying regions. The latter are the source of radiation generated via spontaneous and stimulated emission, which embodies

Tunable photon blockade in a whispering-gallery-mode microresonator coupled with two nanoparticles.

We have theoretically studied the photon statistical properties in a nonlinear whispering-gallery-mode microresonator coupled with two nanoparticles. By tuning the relative position of two

Variable optical chirality in an atomic assisted microresonator

A whispering gallery mode resonator with a cavity-made slot filled atomic vapor is demonstrated, in which the chiral symmetry is broken induced by asymmetric backscattering of counter-propagating
