Query: Plasmonic ultra-broadband polarizers based on Ag nano wire-slit arrays   We propose ultra-broadband reflective and absorptive polarizers in the
visible range using multi-scaled Ag nano wire-slit arrays. The nano arrays can
be tuned from reflective to absorptive by incorporating Ag wires/strips with
different lengths/widths. The ultra-broadband nature of the absorptive array,
with averaged absorption as high as ~80%, is due to the collective excitations
of plasmonic resonances in the Ag wires/strips with different length scales.
The Ag nano wire-slit arrays are realized experimentally by using a simple
two-times shadowing vapor deposition method. They exhibit broadband
transmission difference, in good agreement with simulations. The multi-scaled
Ag nano wire-slit array has potential applications as broadband linear
polarizers and anti-reflective materials in both optics and photovoltaics.
