Abstract :
Woodpile structures for three dimensional photonic crystal were fabricated via two photon polymerization. Resins with high two-photon cross-section undergoes a polymerization and forms the woodpile structure upon irradiation of a 780 nm Ti:sapphire femtosecond laser. The bandgap of woodpile depends on the parameters of woodpile, which can be varied by nano-positioning system.
