WebCavity Effects: Cavity effects refer to coherent interaction of light in the cavity. When light undergoes multiple reflections in a layer it can interact with itself, causing the fields to buildup. As we have seen cavity effects may degrade or enhance the optical performance depending on what exactly you are referring to. WebDec 16, 2024 · “Entanglement-enhanced optical atomic clocks will have the potential to reach a better precision in one second than current state-of-the-art optical clocks,” says lead author Edwin Pedrozo-Peñafiel, a postdoc in MIT’s Research Laboratory of Electronics.
