Spectral light separator based on deep-subwavelength resonant apertures in a metallic film
Spectral light separator deep-subwavelength resonant apertures metallic film
2014/8/6
We propose to funnel, select, and collect light spectrally by exploiting the unique properties of deep-subwavelength resonant apertures in a metallic film. In our approach, each aperture has an ...
Planar Lenses Based on Nanoscale Slit Arrays in a Metallic Film
Planar Lenses Nanoscale Slit Arrays Metallic Film
2009/8/10
We experimentally demonstrate planar lenses based on nanoscale slit arrays in a metallic film. Our lens structures consist of optically thick gold films with micron-size arrays of closely ...
