Two well-known methods for the design of quasicrystal models are used to create
novel nonlinear optical devices. These devices are useful for efficient three-wave
mixing of several different processes, and therefore offer greater flexibility
with respect to the more common periodic nonlinear photonic crystals. We
demonstrate applications for polarization switching as well as multi-wavelength
and multi-directional frequency doubling. The generalized dual grid method is
proven to be efficient for designing photonic quasicrystals for one-dimensional
collinear devices as well as elaborate two-dimensional multi-directional devices.
