Advanced metal nanostructure design for surface plasmon photonic bandgap biosensor device.

This paper is intended to demonstrate the effect of coupled surface plasmon polaritons (SPPs) on the optical response of a one-dimensional metal grating nanostructure patterned by electron beam lithography (EBL) on the silicon surface. Variations of the structure parameters allow continuously tuning of these high-transmission bands across the nanostructure plasmon resonance. This phenomenon gives rise to a selective spectral response and a local field enhancement which can be used in the context of nano-optics.

Enhancement and tunability of active plasmonic by multilayer grating coupled emission.

The effect of coupled mode surface plasmon polaritons (SPPs) on the active emission of a nanostructure grating with organic semiconductor material, Alq(3), on the surface was investigated in this study. We report surface plasmon grating coupled emission (SPGCE) from excited organic layer on metal grating in both organic/metal (2-Layer) and organic/metal/organic/metal (4-Layer) structures. The dispersion relation was obtained from angle-resolved photoluminescence measurement.
