Abstract
We proposed and demonstrated the double layered metallic nano-hole structure using polystyrene beadsprocess to enhance the sensitivity of surface plasmon resonance (SPR). The double layered SPR structures arecalculated using the finite-difference time-domain (FDTD) method for the width, thickness, and period of themetallic nano-hole structures. The thickness of the metal film and the metallic nano-hole is 30 and 20 nm in the214 nm wide nano-hole size, respectively. The double layered SPR structures are fabricated with monolayerpolystyrene beads of 420 nm wide. The sensitivities of the conventional SPR sensor and the double layered SPRsensor are obtained to 42.2 and 52.1 degree/RIU, respectively.
