1. An apparatus comprising:

  • a reflective layer;

    an absorber layer spaced apart from the reflective layer to define a cavity between the absorber layer and the reflective layer, wherein the absorber layer is capable of transmitting light into the cavity, absorbing light, and reflecting light, the absorber layer including a metal layer;

    a stack disposed on a surface of the reflective layer facing the cavity, the stack including a first dielectric layer and a second dielectric layer, the first dielectric layer including a low refractive index material and the second dielectric layer including a high index material; and

    a plurality of matching layers on a surface of the absorber layer facing away from the cavity, the plurality of matching layers including a first matching layer disposed on the absorber layer and a second matching layer disposed on the first matching layer.
