Microstructured and Photonic Bandgap Fibers for Applications in the Resonant Bio- and Chemical Sensors
Figure 4
Band diagrams and schematics of various SPR-based integrated sensor implementations. (a) Single mode waveguide-based sensor. Dispersion relations of a core-guided-mode (solid) and a plasmon (thick dashed). Inset-sensor schematic; of a plasmon (a) and a core mode (b). (b) Multimode waveguide-based sensor. Dispersion relations of the core modes (solid) and a plasmon (thick dashed). Inset-coupler schematic; of a plasmon (a) and a high-order mode (b) at the phase matching point (black circle).
