Optical patterning of multidomain liquid-crystal displays with wide viewing angles
Article Abstract:
A linear photoalignment strategy controls the tilt angle between the long molecular axes and the substrates to provide improved fields of view in liquid-crystal displays. Functionalized substrates exposed to polarized light provide high-resolution patterns in the display plane. A proper control of the angle removes the orientation defects in the alignment pattern imposed on the crystal. The method enables fabrication of stable, multi-domain pixel displays.

Phase matching using an isotropic nonlinear optical material
Article Abstract:
It has been possible to demonstrate phase matching of a difference frequency generation process in a waveguide containing four Alox layers. Perfect phase matching was achieved with a cubic nonlinear material. GaAs is also the material of preference for quantum-well lasers, and research is being undertaken into the possibility of integrating quantum wells in the core of the nonlinear waveguide.
