Multiple surface-plasmon-polariton (SPP) waves are guided by the interface of a metal and a chiral sculptured thin film (STF) at a single wavelength. Spatially multiplexed 4-quadrant chips comprising a lanthanum-fluoride chiral STF embedded with a silver-nanoparticle layer were deposited atop an aluminum-coated glass substrate, each quadrant functioning as an autonomous sensor. The void regions of the chiral STF in each quadrant were in filtrated with sucrose solutions of increasing molarity and deployed in a prism-coupled surface-multi-plasmonics-resonance-imaging (SMPRI) machine. The angular locations of the SPP-wave modes shift as the molarity of the fluid increases, thus demonstrating simultaneous sensing of fluids via SMPRI.
