Abstract

We propose a Ge nanostripe array to realize strong absorption in the near-infrared band. The maximum absorption is approximately 95% around 1310 nm for TE-polarized incidence, which is increased by 4 times compared to the unstructured planar structure with the same thickness. The experimental result verifies the simulated prediction consistently.
