Metamaterials observe photonic spin Hall effect

A metamaterial surface constructed of V-shaped gold nanoantennas was used to obtain the strongest signal yet of the photonic spin Hall effect – a quantum mechanical optical phenomenon that could play a prominent role in the future of computing. Researchers from Lawrence Berkeley National Laboratory amplified the naturally weak effect by measuring polarized light incident on a 2-D sheet of gold nanoantennas whose geometry could be configured by adjusting the length and orientation of the arms of the V’s. The findings could have profound implications for information processing...Read full article
