Microstructured and Photonic Bandgap Fibers for Applications in the Resonant Bio- and Chemical Sensors
(a) Avoided crossing of the dispersion relations of the fundamental core mode (dashed curve) and a THz plasmon-like excitation (thin solid curve) in a porous fiber with a PVDF layer. (b) Losses of a core-guided-mode for two values of the gaseous analyte refractive index (dashed curves). A corresponding amplitude sensitivity curve for a sensor of the refractive index of a gaseous analyte is presented as a thick solid curve.
