Liquid crystal waveguides: Implementation and optical characterization

Liquid crystal (LC) is a unique state of matter that exhibits properties of both liquids and solids. One main property is that the nematic phase allows the possibility to orientate and align molecules in any direction by application of external perturbations such as electric, magnetic field, heat or...

Sumario:Liquid crystal (LC) is a unique state of matter that exhibits properties of both liquids and solids. One main property is that the nematic phase allows the possibility to orientate and align molecules in any direction by application of external perturbations such as electric, magnetic field, heat or pressure. This thesis will study the implementation of LC waveguide samples and its characterization at normal incidence light in a transmission optical setup in two different ways: in-plane (azimuthal rotation) and out-of-plane (polar rotation). This will provide a holistic approach for electro-optical characterization on the change in azimuthal and polar angles of the nematic LC waveguide with reference to the applied voltage.
