| Abstract: | We report FDTD simulation results demonstrating that the optical phase change of surface plasmon polariton-assisted transmission through nanohole arrays in a metal film undergoes a sharp change under resonant conditions. The phenomenon can be explained by various resonant modes between the nanoholes. We further explore the possibility of using this effect for phase-sensitive surface plasmon resonance biosensing applications. |
