Abstract
Optical alignment and strong residual birefringence in a nematic liquid crystal that is stabilized by a polymer network are described. The polymer’s main chain contains an azo dye, which is responsible for the repulsion of the axis of the guest–host system from the electric field of the excitation light.Keywords
