摘要: Direct laser writing by two-photon polymerization of photosensitive materials has emerged as a very promising technique for rapid and flexible fabrication photonic crystals. In this work, silica sol-gel containing the nonlinear optical chromophore Disperse Red 1 is synthesized, employed to fabricate three-dimensional crystals with stop-gaps in near-infrared. The composite material exhibits minimal shrinkage during photopolymerization, eliminating need compensation or support structures.
