  • Patent number: 9298059
    Abstract: The present invention provides a transflective display device which is high in transmittance, can secure sufficient brightness in display, and can display black. A transflective display device 1 includes a display panel 2 and a backlight 3. The display panel 2 includes a substrate 10 having an electrode 12. a substrate 20 having an electrode 22, and an optical modulation layer 30 containing shape-anisotropic members 32. A frequency of a voltage to be applied to the electrodes 12 and 22 is changed so as to rotate the shape-anisotropic members 32. When the shape-anisotropic members 32 are oriented such that their major axes extend in parallel with one of the substrates on which the shape-anisotropic members 32 abut, multiple reflection of incoming light is caused, and thus black is displayed.

  • Patent number: 9244330
    Abstract: Embodiments of the invention provide apparatuses and methods for phase correlated seeding of parametric mixer and for generating coherent frequency combs. The parametric mixer may use two phase-correlated optical waves with different carrier frequencies to generate new optical waves centered at frequencies differing from the input waves, while retaining the input wave coherent properties. In the case when parametric mixer is used to generate frequency combs with small frequency pitch, the phase correlation of the input (seed) waves can be achieved by electro-optical modulator and a single master laser. In the case when frequency comb possessing a frequency pitch that is larger than frequency modulation that can be affected by electro-optic modulator, the phase correlation of the input (seed) waves is achieved by combined use of an electro-optical modulator and injection locking to a single or multiple slave lasers.
