  • Optical device
    Patent number: 6549253
    Abstract: The invention relates to an optical device comprising two substantially parallel substrates with electrode layers on their facing sides for switching an optically active layer which is present between said substrates. Furthermore the present invention relates to a hybrid layer for use in such an optical device. Switching of the layers is enhanced by introducing optically anisotropic material in a porous structure.

  • Glancing angle deposition of thin films
    Patent number: 6206065
    Abstract: A method of making vapor deposited thin films by rotating a substrate in the presence of an obliquely incident vapor flux. The substrate is rotated about an axis normal to the surface of the substrate while depositing a vapor flux, and then paused while depositing vapor flux to cause columns of a thin film to grow obliquely. The resulting thin film exhibits a porosity that is not dependent on the column angle of the resulting thin films.
