Photonic Crystals have the potential for engineered light interaction as directed by the photonic bandgap, a property that details the prohibited propagation region and ultimately the ability to guide light. A so called, photonics-on-chip, would incorporate arbitrary light guiding with functional elements in one package. The realization of such a device is subject to the fabrication paradigms implemented and this thesis is concerned with holographic lithography as a means for creating polymer photonics crystal templates and two-photon polymerization for incorporating light guiding pathways.

In this thesis, the design of the to-be-fabricated structures has been co-opted by computational exploration of the photonic crystals possible under the fabrication paradigms with the photonic bandgap considered as a target for design optimization, and tolerancing. Introduction of defects into photonic crystal templates has been successfully realized with the assistance of a tunable femtosecond oscillator laser after the processing conditions have been investigated and demonstrated.
