Plasmonic components fabrication via nanoimprint
نویسنده
چکیده
A review report on nanoimprinted plasmonic components is given. The fabrication of different metal–dielectric geometries and nanostructured surfaces that support either propagating or localized surface plasmon modes is discussed. The main characteristics and advantages of the nanoimprint technology for the fabrication of various plasmonic structures are outlined. The discussion of plasmonic waveguiding structures focuses on planar waveguides based on metal strips embedded into a dielectric and on profiled metal surfaces. Nanoimprint-based fabrication of two-dimensional nanostructured plasmonic surfaces for enhanced transmission studies and sensor applications is also discussed. Throughout the report, the main fabrication schemes are described, as well as the challenges facing future manufacturing of plasmonic components for device applications.

Plasmonic bar-coupled dots-on-pillar cavity antenna with dual resonances for infrared absorption and sensing: performance and nanoimprint fabrication.
We report the structure, performance and large-area fabrication of a thin plasmonic infrared absorber, termed "bar-shaped disk-coupled dots-on-pillar antenna-array" (bar-D2PA). The bar-D2PAs, which are simple to fabricate, demonstrate the following, experimentally: (i) a different light-absorption resonance for each polarization with the resonance peak tunable by the bar-to-backplane gap and th...

The fabrication and characterization of over millimeter (mm)-scale Au plasmonic structures are reported. Fishnet structures of Au are fabricated by the "bottom-up (direct deposition of alkanethiol)" and "top-down (wet-etching of Au)" combined approach using massively parallel dip-pen nanolithography (DPN). An array of two-dimensional (2D) parallel 55,000 pens was used for the DPN writing of 1-o...
