  Hello,
  You can use a mode source to inject light into the SPP mode in a plasmonic waveguide: https://optics.ansys.com/hc/en-us/articles/360034902153
  You can check the electric field components of the mode to see the polarization. I'm not sure what you mean by sensitivity and detection limit, how to calculate them will probably depend on the device design. These biosensor examples might be helpful for you:
