Time-resolved simulation of the dynamics of a pulse illuminating a microcavity. An optical microcavity or microresonator is a structure formed by reflecting faces on the two sides of a spacer layer or optical medium, or by wrapping a waveguide in a circular fashion to form a ring.
It is illegal to use listening or recording devices that are not permitted for public use. Individuals may only use listening or recording devices within reasonable privacy laws for legitimate security and safety reasons. Many people use listening devices on their own property to capture evidence of excessive noise in a neighbour complaint ...
A reverberation chamber is cavity resonator—usually a screened room—that is operated in the overmoded region. To understand what that means we have to investigate cavity resonators briefly. For rectangular cavities, the resonance frequencies (or eigenfrequencies , or natural frequencies ) f m n p {\displaystyle f_{mnp}} are given by
A resonator is a device or system that exhibits resonance or resonant behavior. That is, it naturally oscillates with greater amplitude at some frequencies, called resonant frequencies, than at other frequencies. The oscillations in a resonator can be either electromagnetic or mechanical (including acoustic). Resonators are used to either ...
The simplest resonator structure that can be used in rf and microwave filters is an LC tank circuit consisting of parallel or series inductors and capacitors. These have the advantage of being very compact, but the low quality factor of the resonators leads to relatively poor performance.

A nanophotonic resonator or nanocavity is an optical cavity which is on the order of tens to hundreds of nanometers in size. Optical cavities are a major component of all lasers , they are responsible for providing amplification of a light source via positive feedback , a process known as amplified spontaneous emission or ASE.
