Paper Abstract

We present a new high-index-contrast material system to realize ridge waveguides and PhC waveguides made of a thin silicon slab embedded in two silica layers. Hence fully symmetrical structures can be etched and two important conditions for low-loss guiding of light can be matched: The symmetry properties of the material avoid polarization mixing and the high index contrast leads to strong confinement of light. Because of operating completely below the lightcone the PhC waveguides allow theoretically lossless guiding of light.
