Cold-cavity thresholds of microdisks with uniform and nonuniform gain: quasi-3-D modeling with accurate 2-D analysis

Dielectric microcavities: Model systems for wave chaos and non-Hermitian physics

“…In practice a microdisk has a finite vertical extension which is usually taken into account within the effective-index approximation; see, e.g., (Smotrova et al, 2005). The central assumption is that the separation ansatz (7) is still valid, ignoring a weak mixing of TM and TE polarizations.…”

Low-threshold lasing eigenmodes of an infinite periodic chain of quantum wires

“…For detailed discussion of the modified eigenproblem approach in the linear modeling of microcavity lasers see [4]. It has been already applied to the threshold analysis of twodimensional entirely and partially active circular microcavities in [6,7], and to one-dimensional quantum-well equipped VCSEL-type layered cavities in [8].…”

Manipulation of Backscattering From a Dielectric Cylinder of Triangular Cross-Section Using the Interplay of GO-Like Ray Effects and Resonances

“…The latter values can grow up more dramatically with ka, for instance, as exp(Re √ εka) for the whispering-gallery modes in a lossless circular cylinder [32]. Still, as in a lossy case Q-factors of internal resonances are limited by the ratio Reε/Imε, one can expect that in real-life circumstances the dielectric prisms with electrical size ka 1/Imε will show no resonances, i.e., display purely GO behaviour.…”
