Theoretical Investigation of an Air-Slot Mode-Size Matcher between Dielectric and MDM Plasmonic Waveguides
Figure 1
The schematics of the proposed ASCs and that show how light couples into the MDM plasmonic waveguide: (a) ASC without the dielectric width expansion, (b) coupling efficiency as a function of the length of the ASC, LASC, for ASC , (c) ASC with the dielectric width expansion, and (d) coupling efficiency as a function of the width of the CDW, , for ASC .
