A system LC-waveguide may be applied in different devices for physical values registration, and optical signal controlling devices. It is important to use a planar waveguide in combination with peculiarity of liquid crystal (LC) materials that are characterised by a high sensitivity to physical values of external influence liquid crystal materials. At present, time waveguides are widely used as elements for signals processing and transmission in optical systems that are realised on different optical effects. The using of palanar waveguide as backplane of LC cell alleviate orientation process of LC layer in contrast to fibre waveguide.
