CONFERENCE PROCEEDINGS FREE ACCESSA simple phase grating is constructed by inserting a liquid crystal layer between two glass plates, on one of which a pair of transparent interdigitated electrodes is formed. The in-plane switching for the liquid crystal molecules alters the grating characteristics. Since one of the transparent plates can be used as a light guide, a light source and a detector mounted on one side of the plate can be connected optically, thus a planar optics configuration is realized. Here, active functions such as switching, wavelength division, power adjustment, etc. are embedded to the connection itself.View full abstractDownload PDF (651K) -

CONFERENCE PROCEEDINGS FREE ACCESSThe color gamut of conventional flat panel displays (FPDs) is not wide enough to reproduce all the colors from all objects. We propose a four-primary color FPDs instead of three-primary colors to expand the color gamut. To achieve four-primary color FPDs, we have developed two technologies, e. g. a scrolled light emitting diode (LED) backlighting of four colors (Red, Green1, Green2, Blue), which is synchronized with the scanning of the displays, and a two sub-frame field sequential driving. As a result, the 15-in. XGA in-plane switching mode - thin film transistor - liquid crystal display (IPS-TFT-LCD) with 122%-NTSC color reproduction has been achievedView full abstractDownload PDF (738K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe studied the features of the newly developed Top and Bottom Contact Field Effect Transistor (TBCFET) with organic semiconductor layers. Pentacene TBCFETs with ca. 0.5μm channel length (L) were fabricated and their transistor properties were measured. The output drain-source currents (I_<DS>) of TBCFET were 1 to 2 orders of magnitude higher than those of ordinary planar type FETs with 100μm channel length. On the other hand, because of the TBC structure, off current tends to become larger in the TBCFET. Therefore, in order to solve this off-current problem, we intentionally formed the Schottky junction at the top electrode/semiconductor interface. As a result, the off current became about 2 orders of magnitude smaller than before the formation of the Schottky junction.View full abstractDownload PDF (490K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe present a potential of phase correction in self-pumped phase conjugate mirrors. Photorefractive phase conjugate mirror allows a stable laser oscillation in a high power CW laser including strong thermal aberration. Phase conjugate mirror based on saturable gain exhibits high phase conjugate reflectivity of >2,100%.View full abstractDownload PDF (451K) -

CONFERENCE PROCEEDINGS FREE ACCESSThe relationship between the microscopic structure, the electronic structure, and the photoabsorption property of individual J-aggregates of the merocyanine dye molecules were investigated by a newly developed analytical microscopic technique using a scanning tunneling microscopy (STM) with nanometer-scale resolution. The relationship between the microstructural features of J-aggregates and the electronic nature of their peculiar photoabsorption property was elucidated experimentally for the first time.View full abstractDownload PDF (627K) -

CONFERENCE PROCEEDINGS FREE ACCESSStructural color is the general term of the phenomenon of coloring due to reflection, interference, diffraction, and scattering of light. It fundamentally differs from the usual coloring by dyestuffs or pigments. Typical structural colors are observed as the reflection of light from the three dimensional crystal lattice that is formed from fine particles of sub-micron size. This study was performed to prepare this type of structural color. We produced monodispersed acrylic particles by emulsion polymerization, and particle size was controlled precisely. The crystal alignment of these particles was achieved by two methods. One is utilizing capillarity which occurs when the emulsion dries, and the other is electrophoresis. Moreover, in order to absorb the scattered light occurring inside the crystal, the particles were dyed with some dyestuffs. By both methods, we succeeded to obtain crystals with beautiful structural colors.View full abstractDownload PDF (601K) -
