摘要

We report a leaky-mode resonant absorber fashioned as one-dimensional nanopatterned ultra-thin films. This simple structure exhibits optical absorbance of approx66percent in the 300-750 nm wavelength band, which is an approx60percent increase relative to a comparable planar reference structure. The transverse-magnetic (TM) polarized light in the approx460-560 nm band is nearly totally absorbed. Applying a backside metal reflector raises the absorbance farther to approx73percent.
