Harry Atwater's group is constantly innovating and recently came up with an interesting concept termed as "Resonance Guided Wave Networks (RGWN)". A RGWN is an optical materials design consisting of power-slitting elements arranged at the nodes of a waveguide network. A typical 2D waveguide network is composed of intersecting metal-insulator-metal waveguides. This type of structure exhibits photonic bands and band gaps at IR wavelengths, as well as localized resonances of Q~80 at telecommunications wavelength.
The full story can be found in the Phys. Rev. Lett paper by Feigenbaum and Atwater:
