    Abstract: The sensing performances of a four layer Bragg fiber based plasmonic biosensor for aqueous solutions using an As2S3 chalcogenide layer are investigated with an analytical method. In comparison with a previously considered fiber structure with a GaP layer, the new geometry has the advantages of a smaller value of the full width at half maximum and a... Show More
