Optical microcavities confine light to small volumes by resonant recirculation. Devices based on optical microcavities are already indispensable for a wide range of applications and studies. For example, microcavities made of active III-V semiconductor materials control laser emission spectra to enable long-distance transmission of data over optical ...

Microcavity quantum superradiance
Journal of Optics B: Quantum and Semiclassical Optics, 2000Two-dipole superradiance in a planar symmetrical microcavity has been investigated for the first time in the space-time domain by a controlled femtosecond excitation of two ensembles of molecules located at a mutual distance R on the plane parallel to the cavity mirrors.

Abstract Optical cavities or resonators having dimensions of the order of cube of the wavelength, are introduced with the definitions of DOM, mode volume, quality factor, finesse, and loss mechanisms in general. The simplest resonator structures, the FP resonator, Bragg gratings and mirrors, and ring resonators and their characteristics ...

Water filling of microcavities
Biomicrofluidics, 2022Cavity-filling is a common phenomenon whereby a fluid fills all or part of a cavity, displacing another immiscible fluid. In this study, we experimentally and theoretically investigate the effects of the cavity aspect ratio, channel width, tilting angle of the cavity leading wall, and inlet flow rate on the morphology of the water-air interface and the

A microcavity biosensor monitors optical resonances in micro-and nanostrucrtures for label-free detection of molecules and their interactions. I will give an introduction to the field of microcavity biosensing and present an overview on the current state-of-the art.

AbstractBoth rich fundamental physics of microcavities and their intriguing potential applications are addressed in this book, oriented to undergraduate and postgraduate students as well as to physicists and engineers. We describe the essential steps of development of the physics of microcavities in their chronological order.

Microcavity lasers potentially will have ultra-low thresholds in the micro ampere range or even lower. The vertical-cavity surface-emitting laser (VCSEL) structure represents the most straightforwardly produceable device which can scale down to ultra-small cavity dimensions and active material volumes.

Tunable photonic crystal microcavities
Applied Optics, 2002We present a method for tuning a photonic crystal microcavity by modulating the index of refraction of the lattice sites within and surrounding the microcavity. The index of refraction can be actively modulated after infiltrating anisotropic liquid crystals into a two-dimensional photonic crystal lattice of air cylinders in silicon.
