Theoretical Investigation of an Air-Slot Mode-Size Matcher between Dielectric and MDM Plasmonic Waveguides
Figure 2
The schematics of the proposed ASCs and that show how light couples into and out of the MDM plasmonic waveguide: (a) ASC #3 without the dielectric width expansion that resulted from connecting two ASCs back to back, (b) ASC with the dielectric width expansion that resulted from connecting two ASCs back to back, (c) transmission coupling efficiency as a function of the length of the MDM plasmonic waveguide, LMDM, for both ASCs and , and (d, e) field distributions of the coupled light at 1550 nm for ASCs and when LMDM = 740 nm.
