Figure 8
(a) Numerical wavelength shift as function of temperature numerically evaluated by using nslab and hslab reported in Fig. 7, and compared with the experimental results (dashed curves) already shown in Fig. 5b. Numerical results (dots) were fitted with smoothing spline method (solid curves). (b) Functions nslab (hslab) evaluated for the three analyzed probes by using the proposed model. The three pathlines are superimposed to a contour plot (dot lines) showing the numerically evaluated resonant wavelengths as function of dielectric slab thickness hslab and RI nslab.
