Paper Abstract

In this paper, we have demonstrated two types of polymer waveguide switches with nematic liquid crystal cladding. Although the higher propagation loss in LC materials hinders them from serving as the waveguide film, it has been common that LC exhibiting a large optical anisotropy and an electrically controllable molecular alignment are applied to investigations of slab-waveguide cut off switching as active medium claddings. For this type of switching geometry, a higher contrast ratio is obtainable because simple TE or TM polarized waves may be supported in the planar polymer waveguide.
