I study a multilayered medium consisting of a metal–dielectric composite film, a spacer layer, and a dielectric Bragg reflector. I demonstrate a greater flexibility over the critical coupling phenomenon [ Tischler et al., Opt. Lett. 31, 2045 (2006) ], whereby nearly all the incident light energy is absorbed by the composite film through suppression of both transmission and reflection from the structure. For a larger volume fraction of the metal inclusions, strong light–matter coupling is shown to lead to almost total absorption at two distinct frequencies.
