    摘要： In an optical waveguide channel device equipped with multiple cores, the distances between cores at the entry edge must be large in order to cause a laser beam to enter each core. On the other hand, the distances at the exit edge must be small. Therefore, the core must have a curved area at which the axis is curved. Further, in order to make it easier to match the spot of the entering beam and the core, the core diameter of the optical waveguide channel device and the beam spot diameter of the entering light are made large. However, in a core having a multi-mode curved area, high-order light is easily excited at the curved area. Therefore, the curved area from the entry edge to the exit edge of each core is made to have a single mode. Consequently, exit light having an essentially Gaussian profile may be obtained.

    摘要翻译： 在配备有多个芯的光波导通道装置中，入射边缘处的芯之间的距离必须大，以使激光束进入每个芯。 另一方面，出口边缘处的距离必须很小。 因此，芯必须具有弯曲的区域，在该区域轴线是弯曲的。 此外，为了使入射光束和光纤的点更容易匹配，光波导通道器件的芯径和入射光的光束直径变大。 然而，在具有多模弯曲区域的芯中，在弯曲区域容易激发高阶光。 因此，从每个核心的进入边缘到出口边缘的弯曲区域被制成具有单一模式。 因此，可以获得具有基本高斯分布的出射光。

    摘要： A fixing apparatus according to an embodiment includes: a first roller; a second roller that forms a nip between the second roller and the first roller and pressurizes a sheet passing through the nip against the first roller; a third roller that is disposed in parallel with the first and second rollers; a fixing belt that is stretched over the first and third rollers; a heater that uniformly heats the fixing belt in a direction of a width of the fixing belt; and a heat-uniformizing member that is a shaft-shaped heat-uniformizing member embedded in the third roller. An effective length in a longitudinal axial direction of the heat-uniformizing member is set to be the same or greater than a width of a predetermined maximum sheet so as to uniformly distribute heat of the fixing belt which is in contact with the third roller in the longitudinal axial direction.
