  4. 3. Liquid Crystals in Guided Wave Optics

    Författare :Giusy Scalia; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antiferroelectric liquid crystals; fully-leaky guided mode; ortho-conics; waveguide; liquid crystals; anisotropy;

    Sammanfattning : Liquid crystals are unique optical materials due to their large effective electrooptic and opto-optic coefficients. Currently, liquid crystals are primarily used in flat-panel dis-plays, but there is also an increasing number of nondisplay applications requiring new types of devices employing materials with unique optical properties.

  5. 4. Optical Investigations of Chiral Liquid Crystals

    Författare :Anders Dahlgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antiferroelectric; de Vries theory; ferroelectric; optical activity; chiral; dielectric tensor; unwinding; liquid crystal; helicoidal; selective reflection;

    Sammanfattning : Optical investigations of course involve experimental work, but a theoretical basis is also needed. The first chapter can hopefully can give the non-expert an insight into the science of liquid crystals. Liquid crystals are optically birefringent, and a review of the phenomenon of birefringence follows in chapter 2. LÄS MER

  7. 5. Structures and Properties of Ferroelectric Liquid Crystal Displays

    Författare :Marek Matuszczyk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smectic; displays; dielectric anisotropy and biaxiality; surface-stabilized structure; dielectric; paraelectric; liquid crystal alignment; electroclinic effect; grey scale; polarization; multiplexing; liquid crystal LC ; orthogonal and tilted phases; chirality; aligning layer; ferroelectric; polyimide; rubbing; light valves and modulators; SSFLC;

    Sammanfattning : Liquid crystals have unique physical properties as they combine the features of solids and liquids. In thermotropic liquid crystals the degree of order varies with temperature resulting in an appearance of intermediate phases. LÄS MER
