Abstract :
In this letter, we present a colorful plasmonic hologram which is polarization sensitive-the diffraction efficiency of transverse magnetic light is more enhanced than that of the transverse electric light. The character is caused by longitudinal plasmonic waveguiding effects in the periodic metal-insulator-metal waveguides. These patterns in the hologram even lead to the merits of wide incident angle and working bands. This letter affords a new approach to fabricate highly efficient and polarization-dependent hologram, which is potentially applicable to stronger anticounterfeiting and compatible with liquid crystal for dynamic 3-D displays.
