Figure 7. The influence of geometrical parameters of groove on the mode conversion of the BSW.

Figure 7.

(a) the mode conversion efficiency Rsp, and (b) the scattering loss of TE-BSW as a function of incidence angle and the depth of groove. The width of groove is fixed at 400 nm. As the depth of groove is fixed at 230 nm, (c) the mode conversion efficiency Rsp, and (d) the scattering loss of TE-BSW as a function of incidence angle and the width of groove.
