    • Deterministic generation of nonclassical photons by producing a dilute gas of exciton-polaritons in a solid-state microcavity that includes a periodic array of potential well traps. A photon-exciton frequency detuning is modulated in the microcavity to produce a polaritonic quantum phase transition from a superfluid state to a Mott-insulator state. The nonclassical photons are then generated simultaneously by radiative decay of exciton-polaritons in the microcavity. The nonclassical photons may be indistinguishable single photons, in which case the dilute gas of exciton-polaritons is produced such that on to average there is one polariton per potential well trap. Alternatively, the generated nonclassical photons may be polarization-entangled photon pairs, in which case the dilute gas of exciton-polaritons is produced such that on average there are two polaritons per potential well trap.
    • 通过在固态微腔中产生激子 - 极化子的稀释气体来确定性地产生非经典光子,其包括潜在阱阱的周期性阵列。 在微腔中调制光子 - 激子频率失谐以产生从超流体状态到Mott绝缘体状态的极化量子相变。 然后通过微腔中的激子 - 极化子的辐射衰减同时产生非经典光子。 非经典光子可能是不可区分的单个光子,在这种情况下,产生激子 - 极化子的稀释气体,使得平均每个潜在的阱陷阱有一个极化子。 或者,所生成的非经典光子可以是偏振纠缠的光子对,在这种情况下,产生激子 - 极化子的稀释气体,使得每个势阱陷阱平均有两个极化子。

    • A fuel injection device has a two-way control valve driven by a two-position actuator. The control valve directly controls oil pressure in a back pressure chamber to control an injection operation of an injection nozzle. A two-position three-way flow passage switching valve operated by control pressure of the control valve selectively connects a control chamber of a pressure intensifier with a fuel supply passage leading to a pressure accumulator or a pressure release passage leading to a low-pressure system to indirectly control oil pressure in the control chamber. The flow passage switching valve starts a pressure intensifying operation in retard of the injection operation. When pressure is supplied to the control chamber, stoppage of the pressure intensification operation and returning operation of the pressure intensifier do not lag behind the injection operation.

    • 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.
