Differential Sensing with Replicated Plasmonic Gratings Interrogated in the Optical Switch Configuration
A new plasmonic configuration is proposed for application in a sensor and 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...
