摘要：

A novel and convenient scheme is proposed to achieve angle insensitive color filtering across a large color gamut by simply altering the thickness of the dielectric layer of a dielectric-metal-dielectric grating structure. The plasmonic filter presents a great feature of angle resolved spectrum response up to 60 degrees and is independent of the azimuthal angle and the polarization state as well so as to construct an omnidirectional filter for practical applications. The color tuning feature of the proposed filter with varied dielectric thickness is attributed to the modulation of the condition for the localized surface plasmon resonance, which bears responsibility for the omnidirectional property of this plasmonic filter. This color-tuning method with a single mold size required can have wide applications in fields of display, colorful decoration, printing, and so forth. (C) 2016 Optical Society of America
