Cavity switch
A cavity switch is a device that changes the properties of a cavity (an optical or microwave resonator) over time. When the cavity’s quality factor (Q) is varied, this is called Q switching. Other properties that can be controlled include the cavity mode volume, resonant frequency, phase delay, and the optical local density of states. Cavity switches are used mainly in telecommunications and quantum electrodynamics research.
