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 …

Square microcavities with high quality factor whispering-gallery-like modes have a series of
novel optical properties and can be employed as compact-size laser resonators. In this …

We study the formation of long-lived states near avoided resonance crossings in open
systems. For three different optical microcavities (rectangle, ellipse, and semistadium) we …

Organic single‐crystalline materials have attracted great attention for laser applications.
However, the fabrication of laser resonators and pattern of crystals are still intractable …

Modes in square resonators are analyzed and classified according to the irreducible
representations of the point group C/sub 4v/. If the mode numbers p and q that denote the …

Achieving single-mode operation and highly directional (preferably unidirectional) in-plane
light output from whispering-gallery (WG)-mode semiconductor microdisk resonators without …

Stable dual-mode lasing semiconductor lasers can be used as a seed source for photonic
generation of optical frequency comb and terahertz carrier. Normal square resonator …

Mode characteristics for two-dimensional equilateral-polygonal microresonators are
investigated based on symmetry analysis and finite-difference time-domain numerical …

Optical resonances in polygonal resonators are due to whispering gallery modes (WGM).
We investigate WGM in regular and deformed hexagonal ZnO microwire resonators. Four …

Radiation loss and resonant frequency shift due to sidewall surface roughness of circular
and square high-contrast microcavities are estimated and compared by use of a boundary …
