After a review of previous work on 12-fold symmetric quasicrystals, I present more recent unpublished theoretical work on dispersion and localisation effects in novel quasicrystal geometries with higher symmetry order. Implications for applications will also be discussed. In addition, recent theoretical and practical work on loss reduction in planar photonic crystal slabs will be presented, addressing in particular the issue of etch depth.
