Abstract :
We report on recent development of surface plasmon polaritons (SPP) excited by a highly focused radially polarized optical vortex (RPOV) beam on a metal surface and its new applications in surface plasmon resonance (SPR) sensing and imaging. The proposed method reveals a direct phase manipulation through an incident structured beam to its counterpart in SPP with dynamic, reconfigurable and high-efficiency advantages.
