Abstract Rough metallic surfaces cause severe scattering to surface plasmon polaritons (SPPs), thereby limiting the SPP transmission efficiency. Here, we propose a general scheme to design ultra-compact plasmonic routers that can confine and guide SPPs on arbitrarily shaped rough surface. Our strategy makes use of recently proposed transformation-invariant metamaterials. To illustrate the advantages of this approach, we perform finite-element simulations, showing that the performance of the designed surface-wave router is robust against the change in thickness. As a result, a λ/6-thick transformation-invariant metamaterial layer can significantly suppress scattering from arbitrarily shaped metallic bumps or crevices. We also give a blueprint to implement such ultracompact surface-wave routers based on periodic metal/ epsilon-near-zero (ENZ) material stackings.

Plasmonic photo-thermoelectric conversion offers an alternative photodetection mechanism that is not restricted by semiconductor bandgaps. Here, we report a plasmonic photodetector consisting of an ultra-thin silver film with nanohole array, whose photodetection mechanism is based on thermoelectric conversion triggered by plasmonic local heating. The detector exhibits a maximum photocurrent at the wavelength of the surface plasmon polaritons, determined by the periodicity of the nanoholes. Hence, the response wavelength of the detector can be controlled via the morphological parameters of the nanohole pattern. The contribution of plasmonic local heating to thermoelectric conversion is verified experimentally and numerically, enabling discussion on the mechanisms governing light detection. These results provide a starting point for the development of other nanoscale photodetectors.
