摘要：

The propagation properties of surface plasmon polaritons (SPPs) along metal heterowaveguide (MHWG)-constructed bending nanowaveguides are investigated by finite-difference time-domain simulation. The results reveal that SPPs can pass through 90 degrees sharp bending MHWGs with higher than 90% propagation efficiency. Further numerical demonstrations of the bending MHWGs in splitters and Mach-Zehnder interferometers imply that MHWGs may find significant applications in highly integrated nanophotonic networks.
