The present paper covers the various photonic crystals(PhCs)structures mimicking real atom-lattice structures in electronic crystals by using the femtosecond laser-induced two-photon photopolymerization of SU-8 resin.The bandgap properties were investigated by varying the crystal orientations in , and of diamond-lattice PhCs.The photonic stop gaps were present at λ=3.88 μm in direction,λ=4.01 μm in direction and λ=5.30 μm in direction,respectively.In addition,defects were introduced in graphite-lattice PhCs and the strong localization of photons in this structure with defects at 2=5 μm was achieved.All the above work shows the powerful capability of femtosecond laser fabrication in manufacturing various complicated threedimensional photonic crystals and of controlling photons by inducing defects in the PhCs samples.
