    Abstract: The present optical waveguide device, which improves the optical phase rotation efficiency with respect to activation voltage, includes: a substrate having electro-optic effects; a Mach-Zehnder optical waveguide formed on the substrate; and a signal electrode. The signal electrode is formed in an integrated manner such that an electric signal for applying the electric field travels from an upper part of either one of the two interference optical waveguides, which form the Mach-Zehnder optical waveguide, to an upper part of the other one of the two, and also, a periodical polarization characteristics region, in which regions opposite to each other in polarization are alternately arranged, being provided for a part of the other one of the interference optical waveguides on the substrate.

    Abstract: The present invention relates generally to an apparatus that increases the conversion efficiency of optical parametric oscillators and also reduces overall system size and susceptibility to vibration. The first embodiment of the present invention incorporates a PPLN OPO architecture which includes mirrored coatings on the entry surface area and exit surface area of a monolithic nonlinear optical medium. The coatings act as mirrors, however, the mirrors are actually affixed to the PPLN element. In the first embodiment of the present invention, the PPLN element is a dual grated element. The second embodiment of the present invention uses a single grated PPLN element.

    Abstract: A phase shifter includes an optical waveguide, a plurality of impurity regions and a plurality of electrodes. The optical waveguide receives an optical input signal and outputs an optical output signal. The impurity regions include respective charge carriers. The impurity regions are disposed in contact with the optical waveguide at respective contact surface, where at least one of the contact surfaces has a zigzag pattern. The electrodes are connected to the respective impurity regions. Application of an electrical signal to at least one of the electrodes phase-shifts the optical output signal with respect to the optical input signal. Therefore, the phase shifter may efficiently vary a magnitude of the phase shift of the optical output signal.

    Abstract: An attenuating counter-propagating (ACP) optical phase modulator introduces zero propagation delay. An optical field is modulated by an electromagnetic field. Within the ACP modulator, the optical field is propagated in an opposite direction to the propagation direction of the electromagnetic field. The electromagnetic field is attenuated within the ACP modulator. In an example embodiment, the length of the modulator is greater than the attenuation length of the electromagnetic field.
