Here the scientists are interested in using the light circulating inside the cavity to make the resonator breathe radially.

She then captured the signal in the superconducting cavity, in an area called the meander, or the resonator.

Depending on the geometric shape of the cavity and the dominant mode, laser emission from such a resonator can be either directional or omnidirectional.

This resonator in the presence of moderate losses serves as an absorbing optical cavity in which the loss can be considered as a perturbation.
