Parallel femtosecond laser fabrication of three-dimensional photonic crystals using the dynamic laser printing technique is demonstrated. Combining a spatial light modulator with a versatile direct laser writing setup, the dynamic laser printing system is able to produce two-dimensional spot arrays in a single shot. High quality three-dimensional polymeric photonic crystals with 90% void uniformity and 60% suppression in transmission were generated. This technique dramatically reduces the fabrication time by two orders of magnitude, compared with the direct laser writing technique.
