Abstract :
Summary form only given. A major drawback of photonic crystal waveguides is the different alignment of the photonic bandgaps (PBGs) in different propagation directions. The symmetry of the underlying lattice (3-, 4- or 6-fold) means the photon multiple scattering is strongly orientation dependent. This has led to the focus on high refractive index materials in which the PBGs at least overlap. We show here a new alternative based on the use of high orientational symmetry quasicrystals, which leads to full PBGs in lower refractive index glasses.
