An optical microcavity is a structure that confines light in a small volume, typically on the micrometer scale. These cavities are designed to enhance the interaction between light and matter, and they are often made up of two or more reflecting surfaces (mirrors) that form a resonant cavity. The specific design can vary, but common examples include Fabry-Pérot cavities and whispering-gallery-mode (WGM) structures.
