Multilayer based interferential-plasmonic structure: metal cluster 3D grating combined with dielectric mirror

摘要

A three-dimensional (3D) photonic microstruc-ture consisting of metal clusters embedded in dielectric matrix is coated with a dielectric mirror. The produced photonic structure shows optical behaviour that combines the interferential effects of the multilayer stack and the surface plasmon resonance of metal clusters. Due to its feasibility and the possibility to widely modify the optical properties of the resulting interferential-plasmonic structure, this approach represents a promising method for the production of novel optical components.
