Abstract:This work demonstrates a tunable liquid crystal polarization converter (LCPC) constructed using two conductive glass substrates that are treated with homogeneous alignment and azimuthal alignment, respectively. The azimuthal alignment surface is deeply rubbed to enhance the alignment performance to tilted LC molecules compared with the homogeneous alignment surface. The LC layer initially presents twisted-azimuthal texture, which is capable of converting linear polarization to azimuthal (radial) polarization w… Show more
