Outline of Final Research Achievements

The spectral controllable optical device was developed based on the molecular orientation of liquid crystal (LC) in LC and polymer phases by light illumination. The optical properties of anisotropic diffraction were induced by the distribution of submicrometer-scale LC droplet in the grating formation using interferometric laser exposure. The cholesteric phase composed of chiral and monomer materials was formed by ultra violet illumination. The cholesteric LC device showed the optical characteristics that reflect the light at the specific bandwidth in the infrared region. The optical evaluation and SEM observation demonstrated the optical performance and the internal structure for the spectral controllable optical device.
