  • Publication number: 20070259215
    Abstract: A method is provided to fabricate a magnetic recording medium which has a magnetic recording layer with reduced grain size. Prior to forming the magnetic recording layer, an intermediate layer is firstly formed, with a boundary phase surrounding and isolating the grains in the intermediate layer. With the formation of the boundary phase, the grain size of the intermediate layer can be successfully reduced. A magnetic recording medium includes an intermediate layer and a magnetic recording layer formed on the intermediate layer. In the intermediate layer, there is formed of segregate grains and a boundary phase which surrounds and isolates the grains, The magnetic layer has magnetic grains formed following the structure of the intermediate layer. The magnetic layer therefore has a relatively smaller grain size than that of conventional medium.

  • Patent number: 7291891
    Abstract: A voltage is applied across gate electrodes (103A) and (103B) in a two-dimensional electronic system (101) placed under a magnetic field, and the polarity of an electric current passed between ohmic electrodes (102D) and (102S) is selected to bring about inversion of electron spins based on a non-equilibrium distribution of electrons in a quantum Hall edge state and to initialize the polarization of nuclear spins. An oscillatory electric field of a nuclear magnetic resonance frequency is applied to coplanar waveguides (104A) and (104B) to control the nuclear spin polarization. The controlled spin polarization is read out by measuring the Hall resistance from ohmic electrodes (102VA) and (102VB).

  • Patent number: 7292613
    Abstract: A micropost microcavity device has a maximum field intensity at the center of a high-index spacer as well as a small mode volume. The device has an approximately half-wavelength thick low-index spacer [400] sandwiched between two quarter wave stacks [410, 420]. The low-index spacer has a high-index subspacer layer [470] positioned at its center. The subspacer layer has a thickness smaller than a quarter wavelength. As a result, the electric field intensity remains a maximum at the center of the spacer where the high-index subspacer is positioned. A quantum dot or other active region [480] may be embedded within the subspacer [470]. The microcavity devices provide, for example, single photon sources, single dot lasers, low-threshold quantum dot or quantum well lasers, or devices for strong coupling between a single quantum dot and the cavity field which can be used as components of photonic integrated circuits, quantum computers, quantum networks, or quantum cryptographic systems.

  • Patent number: 7292746
    Abstract: The present invention provides a set-reset flip-flop operating in an all-optical manner. In this invention, a set pulse is inputted from the setting port. In doing so, only oscillation in set mode is generated at the multi-mode interference portion in a waveguide. As a result, a non-inverting output Q is obtained from the non-inverting output port. This state is then continued even if the set pulse input goes off. Next, a reset pulse is inputted to the resetting port. In doing so, at the multi-mode interference portion, oscillation of light in the set mode is halted, and oscillation in the reset mode occurs. As a result, it is possible to obtain an inverting output Q-bar from the inverting output port. This state is then continued even if the reset pulse goes off.

  • Publication number: 20070252073
    Abstract: A new photogate pixel structure for high performance CMOS Image Sensors is proposed. A new photogate structure is incorporated into the photodiode active-pixel structure. The proposed pixel structure exhibits the dynamic integration capacitance characteristics, which can be controlled by varying the control-voltage at the photogate node. Since the sensitivity is inversely proportional to the integration capacitance, the dynamic integration capacitance characteristics can provide the new functionality and controllability for high sensitivity and high dynamic range. At a low voltage level of the photogate, the pixel sensitivity of the new photogate pixel structure is maximized due to the minimum value of the integration capacitance. At a high voltage of the photogate, the dynamic range of the new structure can be maximized due to the increased well capacity. In addition, at an optimum bias voltage of the photogate, both the dynamic-range and the sensitivity can be simultaneously improved.
