    摘要: An optical phase characteristic measuring apparatus includes a harmonic generator for generating a harmonic wave from a fundamental wave of output light from a light source; a beam splitter for splitting a fundamental-wave component of the output light and a harmonic component; a sample disposed in one of optical paths along which light beams from the beam splitter propagate; a unit that is composed of a signal generator and a mirror and is adapted to modulate the length of one of the optical paths; an optical mixer for mixing the light beams containing the fundamental-wave component and the harmonic component; an optical separator for separating light output from the optical mixer into a fundamental-wave component and a harmonic component; a first optical detector for detecting a fundamental-wave component of an output from the optical separator; a second optical detector for detecting a harmonic component of the output from the optical separator; and a phase detector for detecting the phase difference between AC signals output from the two optical detectors. An optical amplitude/phase characteristic measuring apparatus has a similar structure but includes two light sources, a sum-frequency generator, and other related circuits.

    摘要: In an optical pulse characteristic measuring apparatus, optical pulses to be measured are introduced at the incident end, and split at an beam splitter. A first resultant light beam is reflected by a mirror as a local oscillation light of homodyne detection and is adjusted in a delay element so as to have the same optical path length as that of the second resultant light beam. Subsequently, the first light beam is led to an optical mixer. The second light beam is reflected by a mirror, which is controlled by a signal from a signal generator for modulation of optical path length difference. The second light beam is then reflected by a delay element and is led to the optical mixer. The two light beams combined at the optical mixer are detected by optical detectors. The AC signal component generated by modulation of the optical path length difference is amplified up to a measurable voltage by a differential amplifier. A bandpass filter passes only the AC signal component generated by modulation of the optical path length difference, thereby improving the S-N ratio. By using an AC voltmeter to measure the AC signal component corresponding to the delay of the delay element for correlation length measurement, the auto-correlation signal can be obtained. Accordingly, it is possible to measure the characteristics of optical pulses with high sensitivity and high stability.

    摘要: 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.

    摘要: Lubricating oil supply holes are drilled into a first member that is fitted to a plurality of first annular plates by a spline. Of splines to which each lubricating oil supply hole corresponds, lubricating oil grooves provided in the plurality of first annular plates do not overlap the splines on at least one of the front and rear surfaces of the first annular plates, and therefore lubricating oil flowing out of the lubricating oil supply holes is dispersed in a circumferential direction and flows from the inner periphery to the outer periphery of the first annular plates, rather than gathering in each lubricating oil groove and flowing in an outer peripheral direction. As a result, a force generated by an axial lubricating oil flow, which acts in a direction for causing the second annular plates to contact friction materials on the first annular plates, is suppressed, leading to a reduction in drag torque.

    摘要: 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.
