Abstract

To realize the on-chip detection of cylindric vector beams (CVBs), we propose a method with a chiral plasmonic lens, which make the left-handed circularly polarized part of CVB form a strong plasmonic focus, and the focus position depends on the polarization order of CVB. To avoid the scanning of whole plasmonic field, we change the incident angle of CVB to keep the focus at the center where a waveguide is placed for detection. Then we only needs to measure the incident angle where the light in the waveguide reaches the peak, and the corresponding CVB order can be obtained.
