We present our work on the fabrication of three-dimensional Photonic Crystal templates by holographic lithography and direct laser writing. Both optical methods are highly qualified for the production of top-quality polymeric three-dimensional Photonic Crystals and allow in combination the controlled incorporation of defects and waveguides in large-area structures. Scanning electron micrographs and...

We present recent progress in converting polymer templates into three-dimensional silicon photonic crystals by using a silicon-double-inversion procedure. This has led to woodpiles with both improved structural and optical quality.
Using direct laser writing, we fabricate photoresist templates for 3D-2D-3D photonic crystal heterostructures. The optical properties of these structures are directly compared with scattering-matrix calculations, revealing good agreement, hence good sample quality.
Using direct laser writing, for the first time photonic crystal templates with fundamental stop bands at telecommunication wavelengths are realized. Their measured optical properties agree well with detailed simulations, revealing their excellent optical quality
