Description/Abstract

This paper describes a unique way of designing highly complex photonic nanostructures. hotonic Quasicrystals have far reaching applications in many areas of photonics including light extraction from LEDs and for the fabrication of "slow-light" devices or optical delay lines. However, it is not straightforward to produce the e-beam writer data file to produce an arbitrary symmetry photonic quasicrystal as a "lattice" as such does not exist. The location of the photonic crystal scattering centres are found by an inverse method. Starting with the n-fold diffraction pattern, where n is either 5-fold or in excess of 6-fold symmetry, an inverse Fourier transform is taken which will indicate the real space location of the scattering centres. This procedure greatly simplifies the fabrication of highly complex photonic quasicrystal devices and circuits.
