In this work a number of aspects of planar nanophotonics and photonic crystals have been explored. Various mechanisms of propagation losses in these waveguides were modelled, and a comparison between low-index-contrast structures and high-index-contrast structures was made. The thus acquired insight led to a number of waveguide designs.
The designs were implemented in Silicon-on-Insulator using deep UV lithography. For this, the fabrication process was thouroughly characterised and various obstacles were overcome. The resulting structures are of very high quality and record-low propagation losses for photonic wires were demonstrated.
