Abstract :
We describe, fabricate and demonstrate multi-slotted silicon nanophotonic waveguides, comprised of four low index slots etched longitudinally along the waveguide. The computed modal profiles are well described by supermode theory. We have measured the group index of refraction of the waveguide in the TE and TM polarizations.
