Cavity Continuum

Abstract

   We experimentally demonstrate large arrays of coupled whispering-gallery resonators. By fluorescently marking the ensemble modes, we map their spatial structures along with their spectral distribution.  Our fluorescent micrographs reveal that light can reach distant resonators in various ways, such as while passing through dark gaps, resonator groups, or resonator lines. Our practically infinite periodic array of resonators with quality factor [Q] exceeding 10⁷ might impact a new type of distributed sensors or metamaterial for nonlinear optics and lasers using a cavity continuum that is a distributed material but has high-Q resonators as its unit cells.
