Paper Abstract

A one-dimensional photonic crystal with termination by a noble metal film–a plasmonic photonic-crystal slab–has been theoretically analyzed for its optical response at a variation of the dielectric permittivity of an analyte and at a condition simulating the molecular binding event. We investigate sensing performance by the slab and show that it is tolerant to the variation of probing conditions and the slab's structural parameters. As a consequence, the considered sensor exhibited an enhanced sensitivity and a good robustness in comparison with conventional surface-plasmon and Bloch surface wave sensors.
