(color online) (a) Density plots of the reflectance of the sensing structure as a function of wavelength with a variation of the thickness of Ta2O5 (dH) with the thickness of SiO2 (dL) maintains . (b) Density plots of the reflectance with a variation of dL and . Spectra are calculated for θ = 63° and the other parameters are kept unchanged.
