A Planar Metallic Collimator Based on Controlling Surface Plasmons’s Phase

摘要：

We present numerical study of the optical transmission of a metal film perforated by slits array with different spacing. A planar metallic collimator with phase retardation controlled by the slits space is designed. The analysis results show this structure with appropriate space between the slits can collimate or deflect the transmitted beam,which is attributed to phase retardation of surface plasmons propagating from one slit to the other. The numerical analysis results demonstrate a useful deflecting or collimating function of a planar metallic film in the applied fields of optical storage,optical coupler,nano-optics.
