TL;DR: This article uses selective conversion between free-space waves and spatially confined modes in plasmonic nanoresonators formed by subwavelength metal-insulator-metal stack arrays to show that the transmission spectra through such arrays can be well controlled by using simple design rules, and high-efficiency colour filters capable of transmitting arbitrary colours can be achieved.

TL;DR: External quantum efficiencies are enhanced about 2.5 fold around the peak solar spectrum wavelength of 560 nm, resulting in 35% overall increase in power conversion efficiency than the ITO control device under normal unpolarized light.

TL;DR: The experimental implementation of a bulk metamaterial with a left-handed response to ultraviolet light, based on stacked plasmonic waveguides, yields an omnidirectional left- handed response for transverse magnetic polarization characterized by a negative refractive index.

TL;DR: This work achieves fast, high-contrast electrochromic switching by significantly enhancing the interaction of light—propagating as deep-subwavelength-confined surface plasmon polaritons through arrays of metallic nanoslits, with an electrochrome polymer—present as an ultra-thin coating on the slit sidewalls.

TL;DR: In this paper, a nanostructured color filter based on a metallic resonant waveguide structure capable of extremely high transmission efficiency was proposed, achieving transmission as high as 90% with a variable transmission bandwidth.
