Paper Abstract

Optical angular momentum provides a useful dimension for data multiplexing and quantum entanglement. However, the demultiplexing of optical angular momentum is often performed by complex bulk optics and multiple detectors. Here we demonstrate that chiral plasmonic electrodes can be used to selectively detect optical angular momentum in a compact and integrated format. We demonstrate direct detection of photon spin and investigate methods for the detection of orbital angular momentum.
