Paper Abstract

We present novel 2-dimensional slot waveguide schemes. Such geometries allow high confinement for both quasi-TE and the quasi-TM modes in the lower index slot material. Dependence of quasi-TE and quasi-TM mode properties such as effective index and confinement factors on geometrical and material parameters of different waveguide structures is studied. Optimal structure depends on the targeted functionality. For example, 2-dimensional slot waveguides to achieve non-birefringent structures are presented.
