Femtosecond laser micro-fabrication for tailoring photonic crystals in resins and silica

摘要

We report laser micro-fabrication of photonic crystal structures in silica glass and photopolymerizing resins, and present a detailed analysis of their structural and optical properties. Photonic crystals with 2D triangular lattice and 3D diamond lattice in glass are found to exhibit moderately pronounced photonic pseudogaps. Formation of planar microcarvity is demonstrated in log-pile 3D photonic crystal, laser micro-fabricated in resin.
