Fabrication of photonic crystals and templates by two-photon polymerization technique — •Aleksandr Ovsianikov¹, Ruth Houbertz², and Boris Chichkov¹ — ¹Laser Zentrum Hannover e.V. — ²Fraunhofer-ISC Würzburg

Two-photon polymerization (2PP) is a powerful technology for the fabrication of 3D structures with submicrometer resolution. In this contribution we present our recent results on the fabrication of woodpile photonic crystal structures and investigation of their optical properties. The specific applied photosensitive materials are ORMOCER and SU8. Photonic crystals fabricated in these materials exhibit a bandgap in the near infrared spectral region. First results of template fabrication for the realization of high refractive index Ti:O2 replicas will be demonstrated.
