3D Bi‐chiral Photonic Crystals: Three‐Dimensional Bi‐Chiral Photonic Crystals (Adv. Mater. 46/2009)

Bi-chiral photonic crystals are tailored man-made solids inspired by blue-phase cholesteric liquid crystals. They possess two types of chirality, leading to four different types of bi-chiral structures. In naturally occurring blue-phase liquid crystals, only two of these are thermodynamically stable. On p. 4680, Michael Thiel and co-workers fabricate all four via direct laser writing.
