Paper Abstract

By applying a low level of disorder, in the range of 10 to 20 %, to a translationally symmetric photonic crystal one can obtain the dielectric profile of a rotationally symmetric quasi-crystal. Through the use of a morphing algorithm we study the effects of incrementally applying the disorder to a triangular lattice photonic crystal, converting it to a 12-fold quasi-crystal. Through FDTD simulation, band gap maps and defect states are computed and presented as a function of the morphing process.
