Wavelength-scale light concentrator made by direct 3D laser writing of polymer metamaterials
We report on the realization of functional infrared light concentrators based on a thick layer of air-polymer metamaterial with controlled pore size gradients. The design features an optimum gradient index profile leading to light focusing in the Fresnel zone of the structures for two selected opera...
