Abstract

Here, we demonstrate a proof of principle circular polarization filter based on a far-field interference effect using an array of pairs of simple nanoapertures. We demonstrate computationally and experimentally device performance which show good agreement and close to a 10% difference in transmission through the structure for left- and right-circularly polarized light. This ultracompact device could prove useful for remote sensing and advanced telecommunication applications.
