Spectral shift and sensitivity of the PCS in relation to polymer thickness. (a) The simulated reflection spectra for PCS without and with 100 nm polymer, and the measured spectrum without polymer. (b) Simulated spectral shift of PCS sensor for different polymer thicknesses. (c) RI sensitivity ∂λ/∂n for different polymer thicknesses. (d) Thickness sensitivity ∂λ/∂t for different polymer thicknesses.
