Figure 6. Photonic single-pole double-throw switch.

Figure 6.

(a) SEM image of the gratings (L-G) and grooves (T-G and M-G). The L-G contains two parts, the top part is for the launching of TM-BSW and the bottom for TE-BSW. (b-d) the optical images with different orientations of the incident polarizations. The incident beam covers both the top and bottom parts of the L-G. The double-headed white arrows in (b and d) indicate the orientation of the incident polarization. The scale bar (10 μm) on (a) is applicable for (a-d).
