Abstract
An optical switch combining a Pockels cell and a metamaterial, wherein polarization of an incident light is controlled by a voltage on the Pockels cell to block or pass the incident light. The optical switch has advantages of small size, fast switching, simple structure, and high stability. A plasmonic-EIT kind of optical switch is based on plasmonic hybridization and a plasmonic interaction is controlled by altering a polarization state of the incident light. Therefore, the incident light can be selectively allowed to pass through or blocked according to the polarization thereof.
