We exploit the interaction of light with matter to obtain tailored spectral photonic responses. One strategy is based on 2D and 3D composite complex materials –photonic crystals– in which the matter is structured at the scale of the visible of near-infrared wavelengths. In this case, a photonic band structure emerges in which the optical responses dramatically increase at light wavelengths defined by the geometry. On the other hand, we exploit plasmon responses at metal/dielectric interfaces to obtain enhanced optical properties at specific frequencies. We thus combine magnetic materials with either photonic crystals or plasmon resonators to produce systems with customized magneto-optic spectral responses.
