Paper Abstract

Although slot waveguide structures are widely used in all kinds of optical devices, very few articles focus on the issue of optical isolation of slot waveguides. This article, in an effort to bridge the gap in the available literature, focuses on the aspect of optical isolation of slot waveguides and provides definitive rules for application of different slot waveguides in dense integration of optical links. A slot waveguide with a 48-nm-wide slot was fabricated with electron beam lithography and inductively coupled plasma etching.
