    摘要： An apparatus for monitoring strain in an optical chip in silicon photonics platform. The apparatus includes a silicon photonics substrate shared with the optical chip. Additionally, the apparatus includes an optical input configured in the silicon photonics substrate to supply an input signal of a single wavelength. The apparatus further includes a first waveguide arm and a second waveguide arm embedded in the silicon photonics substrate to form an on-chip interferometer. The second waveguide arm forms a delay line being disposed at a region in or adjacent to the optical chip. The on-chip interferometer is configured to generate an interference pattern serving as an indicator of strain distributed at the region in or adjacent to the optical chip. The interference pattern is caused by a temperature-independent phase shift at the single wavelength of the interferometer between the first waveguide arm and the second waveguide arm.

    摘要： The rotary electric machine main body includes: a stator; a rotor that includes a rotating shaft and that is rotatable relative to the stator; and a supporting body that supports the stator and the rotor. The controlling apparatus includes a power circuit portion that is disposed around the rotating shaft, and that converts electric power that is received from the rotary electric machine main body or electric power that is supplied to the rotary electric machine main body between alternating current and direct current. The power circuit portion includes: a power module; and an electric power interconnecting part that includes a conductor that is connected to a terminal of the power module. The electric power interconnecting part is disposed so as to avoid overlapping with a region of the power module when the power circuit portion is viewed in an axial direction of the rotating shaft.

    摘要： Consistent with one example of the disclosed implementations, a photonic integrated circuit (PIC) may be provided that includes s group of lasers and an arrayed waveguide grating (AWG) disposed on a substrate. Each laser in the group may supply an optical signal, such that each optical signal has a different wavelength. Each laser may be tunable to at least two designated wavelengths, which are separated from one another by a free spectral range (FSR) of the AWG. As a result, the optical signals provided from each laser may be combined by the AWG, regardless of which designated wavelength the optical signals have. Accordingly, a PIC may be provided that has a relatively simple construction but can supply optical signals having tunable wavelengths.

    摘要： Consistent with the present disclosure, an AWG is provided that has grating waveguide groupings that extend between a first free space region and a second free space region. The difference in length (ΔL) between successive grating waveguides differs for each grouping of grating waveguides, such that, for example, the ΔL associated with a given grating waveguide grouping is not an integer multiple of any of the other grating waveguide groupings. The grating waveguide groupings direct images having relatively small wavelength differences to a given output waveguide, and each grating waveguide grouping has an associated passband, which is similar to that of the conventional AWG. Unlike the conventional AWG, however, multiple grating waveguide groupings are included in the same AWG, such that the spectra associated with the grating waveguide groupings combine to provide a transmission characteristic having a passband that is greater than any individual passband. Accordingly, even if the optical signal wavelengths vary or are offset from the center wavelength of the passband, such wavelengths may still be transmitted with less loss.

    摘要翻译： 根据本公开，提供了AWG，其具有在第一自由空间区域和第二自由空间区域之间延伸的光栅波导分组。 对于每组光栅波导，连续光栅波导之间的长度差（＆Dgr; L）不同，例如，与给定光栅波导组合相关联的＆Dgr; L不是任何其他光栅波导的整数倍 分组。 光栅波导分组将具有相对小的波长差的图像分配给给定的输出波导，并且每个光栅波导组具有相关的通带，其类似于常规的AWG。 然而，与传统AWG不同，多个光栅波导分组被包括在相同的AWG中，使得与光栅波导分组相关联的光谱组合以提供具有大于任何单个通带的通带的传输特性。 因此，即使光信号波长变化或偏离通带的中心波长，这样的波长仍然可以以较少的损耗传输。
