An optical cavity refers to a space between two mirrors that traps light waves. It is designed to enhance the interaction and Osciĺlation of light within this space, allowing for the amplification or manipulation of light signals. Full definition
Used especially for communications (e.g. fiber optics), optical circuits may use tiny optical cavities as «switches» that can block or allow the flow of light, similarly to transistors in electronics. (sciencedaily.com)
To measure this twisting caused by light, a small silicon beam inscribed with a high quality optical cavity is attached to the waveguide. (sciencedaily.com)
«These studies open exciting opportunities for realizing new types of low - threshold lasing devices that can be fabricated from solution using a variety of substrates and optical cavity designs for applications ranging from fiber optics and large - scale lasing arrays to laser lighting and lab - on - a-chip sensing technologies,» Klimov said.
