Paper Abstract

We report various photonic crystals (PhCs) structures by using the femtosecond laser-induced two-photon photopolymerization of SU-8 resin. The bandgap properties were investigated by varying the crystal orientations in <111>, <110> and <100> of diamond-lattice PhCs. The photonic stop gaps were present at λ=3.88 μm in <111> direction, λ=4.01 μm in <110> direction and λ=5.30 μm in <100> direction respectively. In addition, defects were introduced in graphite-lattice PhCs and the strong localization of photons in our structure with defects at λ=5 μm was achieved. All the above work shows the powerful capability of femtosecond laser fabrication in manufacturing various complicated three-dimensional photonic crystals and of controlling photons by inducing defects to the PhCs samples.
