Cover Story: A new plasmonic configuration is demonstrated for the detection of variations in the bulk refractive index of solutions. The configuration consists of monitoring two diffracted orders resulting from the interaction of a TM-polarized optical beam incident on a grating, operating based on an effect termed the “optical switch”. These two diffracted orders enable differential measurements which cancel the perturbations common to both, leading to an improved detection limit. Bulk sensing is demonstrated under intensity interrogation via the injection of solutions comprising glycerol in water into a fluidic cell. A limit of detection of about 10–6 RIU was achieved. The optical switch configuration is easy to implement and is cost-effective, yielding a highly promising approach for the sensing and the real-time detection of biological species. View this paper
