Abstract
Slot waveguides based on TiO<sub>2</sub> nanowires are numerically analyzed in the visible spectrum. The
modal properties and the sensing capabilities of a conventional slot waveguide
are investigated at an operating wavelength of 635 nm. Furthermore, a novel
slot waveguide configuration called Layer-slot (L-slot) is proposed and discussed.
The numerical results show that L-slot waveguides permit to achieve field
confinement and sensing properties with values comparable with conventional
slot waveguide, but with a strongly simplified fabrication process.
