Metamaterial-based reflector, optical cavity structure including the same and vertical cavity surface emitting laser

摘要

Provided is a metamaterial-based reflector including a first metamaterial layer including an array of first nanostructures, and a second metamaterial layer provided on the first metamaterial layer, the second metamaterial layer including an array of second nanostructures, wherein an arrangement of the second nanostructures is different from an arrangement the first nanostructures.
