“…Surface plasmon resonance has lots of applications in chemical and biological sensing [5,6] as a small change in optical properties of the dielectric sensing medium adjacent to the metal layer can be measured with high precision [7][8][9]. Previously both theoretical and experimental studies have been carried out in the field of SPR-sensors [10][11][12][13][14][15].…”

A semiconductor prism coupler based nanoplasmonic sensor consisting of a high refractive index (RI) silicon prism, a gold (Au) metal film and different amino acids was is used as a dielectric samples for sensing in the in the Attenuated Total Internal Reflection (ATIR) mode. An additional silicon nano-layer has been used for increasing stability and sensitivity of the surface plasmon resonancesensor which enhances of the evanescent field near the metal-analyte interface compared to the traditional three layer structure. Positional swap of the silicon nano-layer from above the metal surface to below the metal surface causes further enhancement of the evanescent field near the metal-analyte interface. Performance of the nano-plasmonic sensors depending upon the high refractive index silicon prism, additional silicon nano-layer and swapping mechanism is discussed with the help of sensing performance for different amino acids with corresponding image response for the proposed nano-plasmonic sensor in a MATLAB environment.

A Kretschmann-Raether prism-based three-layer structure consisting of a prism, gold (Au) metal film, and dielectric sample has been investigated with the use of admittance loci method in attenuated total internal reflection mode. High index prism materials like silicon, chalcogenide (2S2G), and SF14 have been used to study their effect on surface plasmon resonance (SPR) sensing (at 1200-nm wavelength) in infrared region by corresponding admittance loci plots and also by SPR sensing curves. The performance of the sensor based on the choice of the prism material has been discussed with the help of sensitivity plots giving due importance to the dynamic range of the designed sensor.
