Abstract

We investigate photonic design strategies for thermal emission control based on multi-resonator systems. Metamaterial resonators incorporating phase-change materials provide a temperature-tunable response. We identify a layer design for which the radiated power can be designed to either increase or decrease across a phase transition, simply by varying resonator length. Systems supporting both bright and dark modes offer increased design flexibility. We illustrate the use of tunable dark-dark coupling to extinguish thermal emissivity peaks.
