Reviews of Electromagnetics, Vol. I, 2022. Vision paper DOI: 10.53792/RoE/2022.1/22003. AUTHORS: Christina Spaegele, Federico Capasso, Michele Tamagnone, Abstract: We generalize the concept of open optical cavity using one or more reflective metasurfaces instead of two curved mirrors. We provide a simple mathematical framework to describe it in the framework of Maxwell’s equations and examples of applications to lasers and quantum emitters. Less
