Abstract
Fabrication technology, which allows a substantial decrease of the plasmonic propagation loss for both plasmon-friendly metals like Au, Cu or Al and plasmon-unfriendly metals like Co, Fe or Cr, has been developed and experimentally demonstrated. Optimization of the optical confinement is used to reduce the propagation loss below 1 dB per plasmonic device.
