Mode division multiplexed holography by out-of-plane scattering of plasmon/guided modes

We design and demonstrate a type of multiplexed hologram by nanoscatterers inside a dielectric-loaded plasmonic waveguide with guided-wave illuminations. The mode division multiplexed hologram(MDMH) is fulfilled by the scattering of guided waves to free space with respect to different modes. According to different mode numbers, these guided modes have different responses to the multiplexed hologram, and then give rise to different holographic images in reconstructions. In experiments, we show two kinds of MDMHs based on TM_0∕TE_0 and TE_0∕TE_1 modes as examples. Our approach could enrich the holography method that favors on-chip integration.
