TL;DR: In this paper, the authors demonstrate that by monolithically integrating graphene with a Fabry-Perot microcavity, the optical absorption is 26-fold enhanced, reaching values >60%.

TL;DR: It is shown that exceptional points can be conveniently induced in a photonic molecule laser by a suitable variation of the applied pump, including a strongly decreasing intensity of the emitted laser light for increasing pump power.

TL;DR: Analysis, based on a microscopic quantum theory, shows that the nonlinear polariton splitting, a signature of this regime, is a dynamical effect arising from the self-interaction of the collective electronic polarization with its own emitted field.

TL;DR: In this system, a metal-dielectric-metal microcavity combined with quantum well intersubband transitions is an ideal system for the generation of cavity polariton states in the terahertz region.

TL;DR: An experimental and theoretical study of the optical properties of metal-dielectric-metal structures with patterned top metallic surfaces, in the THz frequency range, demonstrating that these structures provide an efficient and controllable way to convert the energy of far field propagating waves into near field energy.
