“…Optical rewritable technology (ORW) [1,[3][4][5][6][7][8][9][10][11][12][13][14] is a modified method of azo-dye photoalignment that possesses traditional high azimuthal anchoring energy, up to 2x10 -4 J/m 2 , and has a unique feature of reversible in-plane aligning direction reorientation, i.e. rotation perpendicular to the polarization of an incident light.…”
