Photonic quasicrystals for general purpose nonlinear optical frequency conversion
Ron Lifshitz, Ady Arie, Alon Bahabad
We present a general method for the design of 2-dimensional nonlinear photonic quasicrystals that can be utilized for the simultaneous phase-matching of arbitrary optical frequency…

The definition of quasicrystals
Ron Lifshitz
It is argued that the definition of quasicrystals should not include the requirement that they possess an axis of symmetry that is forbidden in periodic crystals. The term "quasicr…
