Strong coupling in planar metamaterials — •Manuel Gonçalves¹, Hayk Minassian², and Armen Melikyan³ — ¹Ulm University, Ulm, Germany — ²A. Alikhanyan National Laboratory (YerPHI), Yerevan, Armenia — ³Russian-Armenian University, Yerevan, Armenia

Strong coupling is a regime of matter-radiation interaction in a resonant cavity where both the decay rate of the excited state of the matter and the loss rate of the radiation in the cavity are smaller than the coupling strength of matter with radiation. This is a special case of modified spontaneous emission. Fast decay of excited matter state and large cavity loss lead to the more probable Purcell enhancement of spontaneous emission. However, there is strong coupling beyond the quantum optical realm. In classical systems an interaction regime of coupled resonators with similar properties to the quantum case can be produced.

We show how coupled planar optical resonators can be fabricated and present their optical properties. For some configurations the classical analogue of the quantum strong coupling is achieved. Furthermore, higher degrees of interaction between resonators can be achieved and an analogy with the ultrastrong coupling regime of quantum optical systems can be established.
