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.

结合“等离子体友好”和“等离子体不友好”金属的低损耗等离子体波导的制造技术

已经开发出制造技术并进行了实验证明，该技术可以显着降低“等离激元友好”金属（如金、铜或铝）和“等离激元不友好”金属（如钴、铁或铬）的等离激元传播损耗。光学限制的优化用于将每个等离子体器件的传播损耗降低到 1 dB以下。
