This is a review on theoretical and experimental studies on dielectric microcavities, which
play a significant role in fundamental and applied research. The basic concepts and theories …

There are numerous physical situations in which a hole or leak is introduced in an otherwise
closed chaotic system. The leak can have a natural origin, it can mimic measurement …

Advances in processing technology, such as quantum‐well structures and dry‐etching
techniques, have made it possible to create new types of two‐dimensional (2D) microcavity …

Recently, it has been shown that spiral-shaped microdisk cavities support highly
nonorthogonal pairs of copropagating modes with a preferred sense of rotation (spatial …

In wavelength-scale cavities with chiral-symmetric geometry, wave optical effects can
introduce local chirality, that is, a spatial separation of the clockwise and counterclockwise …

In order to simulate observational and experimental situations, we consider a leak in the
phase space of a chaotic dynamical system. We obtain an expression for the escape rate of …

We present experimental and numerical studies of broad-area semiconductor lasers with
chaotic ray dynamics. The emission intensity distributions at the cavity boundaries are …

The chaotic ray dynamics inside dielectric cavities is described by the properties of an
invariant chaotic saddle. The localization of the far-field emission in specific directions …

Light emission from a dielectric cavity with a stadium shape is studied in both ray and wave
models. For a passive cavity mode with low loss, a remarkable correspondence is found …

We obtain a description of the Poincaré recurrences of chaotic systems in terms of the
ergodic theory of transient chaos. It is based on the equivalence between the recurrence …
