- 30‐1: Invited Paper: Chiral liquid crystal layers with patterned photoalignment for thin diffractive optical components Kristiaan Neyts Migle Stebryte Rohan Sharma Jeroen Beeckman Inge Nys SID Symposium Digest of Technical Papers The ability of liquid crystal to self‐organize into complicated structures can be harnessed in applications such as thin film optical devices, diffraction gratings or smart windows. In this work we focus on liquid crystal layers in contact with one or two substrates that have been patterned by photoalignment. This leads to geometric phase gratings, in which the phase of transmitted or reflected light depends on the location on the substrate. It has been shown that geometric phase gratings with uniform rotation can achieve very high diffraction efficiencies (>90%) for incident light that is circularly polarized. 10.1002/sdtp.17049 http://onlinelibrary.wiley.com/termsAndConditions#vor
