Fabrication of periodic complex photonic crystals constructed with a portion of photonic quasicrystals by interference lithography

By using a single-beam optical interference lithography we fabricated a kind of periodic complex photonic crystals constructed with a portion of photonic quasicrystals. The periodic photonic crystals show the photonic bandgap properties of the original photonic quasicrystals but maintain the periodicity in long range so that their photonic band structures can exactly be calculated in theory. Diverse structures were fabricated by real time modulating the phase relation of the interference beams. The complex photonic crystal materials presented here may provide an example for creating diverse photonic structures for effectively manipulating electromagnetic properties.
