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 convenient to denote cavity frequencies with a complex number ~ = /, where = (~) is the angular resonant frequency and = (~) is the inverse of the mode lifetime. Cavity perturbation theory has been initially proposed by Bethe-Schwinger in optics [1], and Waldron in the radio frequency domain. [2]
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.
A loop-gap resonator (LGR) is an electromagnetic resonator that operates in the radio and microwave frequency ranges. The simplest LGRs are made from a conducting tube with a narrow slit cut along its length. [1] [2] The LGR dimensions are typically much smaller than the free-space wavelength of the electromagnetic fields at the

A computer-simulated ring resonator depicting continuous wave input at resonance. An optical ring resonator is a set of waveguides in which at least one is a closed loop coupled to some sort of light input and output. (These can be, but are not limited to being, waveguides.)
In addition to cost and size, other advantages that dielectric resonators have over conventional metal cavity resonators are lower weight, material availability, and ease of manufacturing. There is a vast availability of different dielectric resonators on the market today with unloaded Q factor on the order of 10000s.
As of 2022 there are two known structures for thin-film bulk acoustic wave (BAW) resonators: free-standing [19] and solidly mounted (SMR) resonators. [20] In a free-standing resonator structure air is used to separate the resonator from the substrate/surrounding. The structure of a free-standing resonator is based on some typical manufacturing ...
