Void channel microstructures in resin solids as an efficient way to infrared photonic crystals

The generation of continuous-void polymer microstructures and void channel based infrared photonic crystals was reported. It was demonstrated that void channel microstructures could be fabricated inside a commercially available precured photopolymer resin, which makes up a transparent bulk solid. It was shown that channel size, surface quality and high density channel vicinity depended on scanning speed and laser intensity.
