Two-photon polymerization (2PP) is a powerful technique for the fabrication of 3D micro- and submicro-structures. By applying laser powers that are only slightly above the polymerization threshold, 3D structuring of photosensitive materials with a resolution down to 100 nm can be realized. Here we report on woodpile photonic crystal structures fabricated in organic-inorganic hybrid polymers (Ormocers) and investigation of their optical properties. The fabricated crystals possess a photonic band gap in the near infrared spectral region. The polymeric woodpile structures can be used as templates for the fabrication of highly refractive TiO2 replicas. First results in this direction are presented.
双光子聚合（2PP）是一种用于制造三维微结构和亚微结构的强大技术。通过施加仅略高于聚合阈值的激光功率，可以实现分辨率低至100纳米的光敏材料的三维结构化。在此，我们报告了在有机-无机杂化聚合物（Ormocers）中制造的木堆光子晶体结构及其光学性质的研究。所制造的晶体在近红外光谱区域具有光子带隙。聚合物木堆结构可用作制造高折射率TiO2复制品的模板。本文展示了在这个方向上的初步成果。
