文摘
Electrically tunable binary liquid crystal (LC) diffraction grating has been designed and fabricated in a simple technique using an LC composite containing photo-curable LC pre-polymer. The binary grating consists of alternating stripes of homeotropic monodomain and non-aligned multidomain. The diffraction efficiency can be modulated by an applied electric field, and is independent of the polarization of incident light.
