Abstract

Manipulation of polarization states is an important feature of many applications including in telecommunication, remote sensing and photonic computing technologies. Here we present two plasmonic nanoaperture based devices for creating and filtering circularly polarized light. One acts as an ultra-compact quarter wave plate, the other, based upon a planar chiral design, leads to asymmetric transmission of left and right circularly polarized light.
