  • Patent number: 8228472
    Abstract: A liquid crystal lens cell comprises a pair of flat layers with the liquid crystal lens supported between the layers. One of the layers supports a planar electrode made of ITO. The other electrode, also formed of ITO, is supported in the center of the opposing substrate and projects downwardly toward the center of the liquid crystal layer. A power supply creates a potential difference between the two electrodes and accordingly imposes a non-uniform electric field on the liquid crystal modules which aligns them in which a way as to act as a lens. By varying the voltage between the two electrodes the focal length of the lens may be controlled. A central electrode may be in the form of a beam or of a pointed tip. In other embodiments of the invention an electrode having a central hole may be associated with the central electrode or the planar electrode.

  • Patent number: 8078015
    Abstract: In an optical modulator, lights that have been branched by an input optical branching section are input via curved waveguides to a plurality of optical modulation sections arranged in parallel on the same substrate. In the optical modulation sections, optical branching sections of an MZ type optical waveguide are arranged shifted to an output side in the longitudinal direction (x direction) of the substrate, corresponding to an arrangement of input ends of signal electrodes. As a result, even if the input ends of the signal electrodes of the respective optical modulation sections are arranged side by side with a predetermined spacing on one side face of the substrate, input light can be applied to the respective optical modulation sections at low loss, without incurring an increase in the drive voltage.

  • Patent number: 8050531
    Abstract: A high efficiency electro-optic dendrimer based technology for nanophotonic integrated circuit devices is presented. In particular, a high power terahertz (THz) source is implemented using an electro-optic dendrimer via electro-optic rectification. Electro-optic rectification provides inherent power scalability, because, pump-THz conversion is not limited either by emission saturation or by heat dissipation. Low dielectric loss and high electro-optic coefficient of dendrimer along with a waveguide structure provides higher output power and tunable THz power generation. A dendrimer fiber array is also disclosed by means of which the input/output signals are connected to multiple components and devices.
