A chemical sensor of refractive index variations, which possesses prescribed resolution, is designed, implemented and tested. Enhancement of coupling forces by the Bloch surface waves is achieved by incorporating a one-dimensional (1-D) photonic crystal (PC) into the classical Kretschmann arrangement of surface plasmon resonance. The numerical optimization approach was used to establish geometrical parameters of the photonic crystal with prescribed material constituents. The number of layers, their thicknesses, and a specific role of the binding dielectric layer between the PC and the metallic film are discussed in detail. Experiments with optimally designed sensor samples compare favourably with model simulations.
