Data supporting the publication "Accurate dipole radiation model for waveguide grating couplers".

This dataset supports the publication: Zhen Liu, Mohamed A. Ettabib, James S. Wilkinson, Michalis N. Zervas. (2023) "Accurate dipole radiation model for waveguide grating couplers" . The excel file contains all experimental data used for generating Fig.2 to Fig.4 : 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.
