Description:
The excel file contains all experimental data used for generating Fig.2 to Fig.4

The figures are as follows:

Fig. 2:  CE and WGC parameters for different core indices, with core thickness selected to maximize the surface intensity; (a) CE on the left y-axis in blue and joint loss on the right y-axis (b) WGC etch depth (left axis) and grating period (right axis). Dots:  numerical [from [2]), solid line: theoretical, dashed line: theoretical without joint loss.

Fig. 3:  Total CE and WGC parameters for different Si core thickness; (a) WGC etch depth (left axis-red) and grating period (right axis-blue), (b) CE (left axis �C blue) and joint loss (right axis-red). Solid lines: theoretical result; dots: numerical results from [2]. 

Fig. 4: (a) Normalized attenuation coefficient   ��_tot (left axis - solid lines), and joint loss (right axis - dashed lines) as a function of etch depth; (b) total CE as a function of grating depth, for different core thicknesses.
