Photonic Crystals can be viewed as semiconductors for light. Despite intensive efforts throughout the past decade, the holy grail of inexpensive fabrication techniques for high-quality, large-scale three-dimensional Photonic Crystals with photonic gaps in the telecommunication range or even in the visible remains elusive. Here, we review our corresponding work along the lines of two compatible and complementary techniques, namely holographic lithography and direct laser writing. Results from optical spectroscopy are compared with detailed theoretical calculations, revealing the high quality of the structures.
