Photonic components based on structured metallic elements show great potential for device applications where field enhancement and confinement of the radiation on a subwavelength scale is required. In this paper, we report on a detailed study of a prototypical metallo-dielectric photonic structure, where features well known in the world of dielectric photonic crystals such as bandgaps and defect modes are exported to the metallic counterpart. Such a structure may have interesting applications in infrared science and technology, for instance, in quantum well infrared photodetectors, narrowband spectral filters, and tailorable thermal emitters.

Abstract
Photonic components based on structured metallic elements show great potential for device applications where field enhancement and confinement of the radiation on a subwavelength scale is required. In this paper, we report on a detailed study of a prototypical metallo-dielectric photonic structure, where features well known in the world of dielectric photonic crystals such as bandgaps and defect modes are exported to the metallic counterpart. Such a structure may have interesting applications in infrared science and technology, for instance, in quantum well infrared photodetectors, narrowband spectral filters, and tailorable thermal emitters.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
