Physicists become acquainted with special functions early in their studies. Consider our
perennial model, the harmonic oscillator, for which we need Hermite functions, or the …

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 …

A semiclassical theory of single and multimode lasing is derived for open complex or
random media using a self-consistent linear response formulation. Unlike standard …

Chaos is a phenomenon that occurs in many aspects of contemporary science. In classical
dynamics, chaos is defined as a hypersensitivity to initial conditions. The presence of chaos …

Conventional nanophotonic schemes minimise multiple scattering to realise a miniaturised
version of beam-splitters, interferometers and optical cavities for light propagation and …

The far-field emission of two-dimensional stadium-shaped microlasers is investigated.
Stadium-shaped microcavities based on a laser dye embedded in a polymer matrix have …

Dielectric microcavities are widely used as laser resonators and characterizations of their
spectra are of interest for various applications. We experimentally investigate microlasers of …

The limaçon-shaped semiconductor microcavity is a ray-chaotic cavity sustaining low-loss
modes with mostly unidirectional emission patterns. Investigating these modes …

A self-consistent integral equation is formulated and solved iteratively which determines the
steady-state lasing modes of open multimode lasers. These modes are naturally …

We report the onset of wave chaos in a real-world vertical-cavity surface-emitting laser. In a
joint experimental and modeling approach we demonstrate that a small deformation in one …
