Abstract


Photonic metamaterials made of graded photonic crystals operating near the bandgap region are proposed for light manipulation around l=1.5┬Ám. Proof-of-concept structures have been studied using Hamiltonian optics and FDTD simulation, fabricated, and characterized using far-field optical measurements. Experimental results are in good agreement with predictions, showing the interest of graded photonic crystals as an (ultra-low loss) alternative solution to the use of metamaterials combining dielectric and metallic materials with sub-wavelength unit cells.
