FIG. 1.

(Color online) (a) Band diagrams of a Gaussian like core mode of a PC waveguide (red) and a plasmonic mode (blue). Two waveguide designs are presented demonstrating that phase matching point (black circles) can be chosen at will. In the inset—sensor structure; of the TM modes of a metallic layer (left) and a Gaussian-like core mode of a PC waveguide (right).

FIG. 2.

(Color online) Dispersion relations of the core guided (thin red line) and plasmon (thick blue lines) modes. Filled light blue regions define the TM polarized bulk states of a periodic reflector, while clear region defines a TM band gap. By design, effective refractive index of a core guided mode can be made significantly smaller than that of a waveguide core material.

(Color online) Sensitivity (relative change in the transmitted power) of a proposed PCW SPR sensor to the thickness of a thin biolayer of deposited on the top of a gold film.
