Strong coupling of in-plane plasmon modes and their control    [PDF]

Sachin Kasture, Prasanta Mandal, S. Dutta Gupta, Venu Gopal Achanta
We show anti-crossings due to strong in-plane coupling of plasmon modes in dielectric-metal-dielectric structure with top 2D dielectric pattern. Experimentally measured anti-crossing widths are compared with those calculated by coupled mode theory. It is shown that the coupling strength of the plasmon modes can be controlled by the orientation of the sample.
