Distribution of the normalized electric field intensity for the different reflectance peaks for two refractive index values (RI = 1.3 and 1.8). The electric field distributions are presented at (a) λ = 1.58 µm, (b) λ = 1.81 µm, and (c) λ = 2.22 µm wavelength points for RI = 1.3 of the analyte with cGST phase of the GST material. The electric field distributions are presented at (d) λ = 1.5 µm, (e) λ = 1.81 µm, and (f) λ = 2.05 µm wavelength points for RI = 1.8 of the analyte.
