  • Patent number: 7953309
    Abstract: An optical fiber, which has a zero-material dispersion wavelength equal to or greater than 2 ?m, and a high nonlinear susceptibility ?3 equal to or greater than 1×10?12 esu, and uses tellurite glass having sufficient thermal stability for processing into a low loss fiber, employs a PCF structure or HF structure having strong confinement into a core region. This enables light to propagate at a low loss. The size and geometry of air holes formed in the core region, and the spacing between adjacent air holes make it possible to control the zero dispersion wavelength within an optical telecommunication window (1.2-1.7 ?m), and to achieve large nonlinearity with a nonlinear coefficient ? equal to or greater than 500 W?1 km?1.

  • Publication number: 20100134473
    Abstract: In a liquid crystal display device performing alternating-current driving, at least one of a gate voltage amplitude Vgp?p(p) upon application of a positive polarity voltage and a gate voltage amplitude Vgp?p(n) upon application of a negative polarity voltage is changed in accordance with a liquid crystal driving frequency. Thus, an effective value of a liquid crystal application voltage in a positive polarity is set to be equal to an effective value of a liquid crystal application voltage in a negative polarity irrespective of the liquid crystal driving frequency, so that flicker is prevented from occurring when the liquid crystal driving frequency is switched. As the liquid crystal driving frequency is low, a gate low voltage Vgln after application of the negative polarity voltage is set to be low. Thus, a leak current from a TFT is reduced in the negative polarity, and a liquid crystal element is improved in voltage holding ratio.
