摘要： A multi-core fiber of the present invention employs the multi-core fiber mode, which corresponds to the “uncoupled” operation aspect in which individual cores are used independently for single-mode transmission, to perform space division multiplexing transmission using a multi-core fiber in which multiple single-mode cores are stored in one optical fiber. More specifically, the multi-core fiber of the present invention forms an uncoupled multi-core fiber that makes individual cores correspond to single-mode, independent transmission channels.

摘要： Optical resonators are vertically coupled on top of bus waveguides, and are separated from the waveguides by a buffer layer of arbitrary thickness. The vertical arrangement eliminates the need for etching fine gaps to separate the rings and guides, and reduces the alignment sensitivity between the desired position of the resonator and bus waveguides by a significant degree. The resonator and bus waveguides lie in different vertical layers, and each can therefore be optimized independently. A ring resonator can be optimized for higher index contrast in the plane, small size, and low bending loss, while the bus waveguides can be designed to have lower index contrast in the plane, low propagation losses, and dimensions that make them suitable for matching to optical fibers. The waveguides can also have any lateral placement underneath the ring resonators and are not restricted by the placement of the rings. Furthermore, with the resonators lying on the top layer of the structure, they are easily accessed for tuning and trimming.

摘要翻译： 光学谐振器垂直耦合在总线波导的顶部，并且通过任意厚度的缓冲层与波导分离。 垂直布置消除了蚀刻精细间隙以分离环和引导件的需要，并且在显着的程度上降低了谐振器和总线波导的期望位置之间的对准灵敏度。 谐振器和总线波导位于不同的垂直层中，因此可以独立地进行优化。 环形谐振器可以针对平面内的较高折射率对比度，小尺寸和低弯曲损耗进行优化，而总线波导可以设计成具有较低的平面折射率对比度，低传播损耗和尺寸，使其适合于匹配 到光纤。 波导还可以在环形谐振器下方具有任何横向放置，并且不受环的放置的限制。 此外，由于谐振器位于结构的顶层，所以它们容易被访问以进行调谐和修整。

摘要： In a multicore fiber in which multiple single mode cores are stored in one optical fiber, the multicore fiber has a lattice-point arrangement in which multiple lattice points are periodically arranged two-dimensionally with translational symmetry and rotational symmetry or one of translational symmetry and rotational symmetry and, in that lattice-point arrangement, multiple cores are arranged with the lattice points of the lattice-point arrangement as reference positions. By giving different perturbations to the propagation constants of the cores, the propagation constants of the cores are each varied from the original propagation constants. Because of the variation in the propagation constants, the core-to-core coupling amount, which is dependent on the varied propagation constants, fall below a predetermined setting amount. Suppressing the coupling between homogeneous cores in this way reduces the distance between the homogeneous cores, thus increasing the core density of the multicore fiber without increasing the types of heterogeneous cores.

摘要： A multi-core fiber for accommodating multiple single mode cores in one optical fiber is provided with multiple types of non-identical cores having different propagation constants. Each of the multiple types of non-identical cores includes a core part and a cladding part covering an outer periphery of the core part. The cladding part has a double cladding structure including a first cladding for surrounding an outer periphery of the core part and a second cladding on the outer side of the first cladding. In the multiple types of non-identical cores, an optical electromagnetic profile in the core part and the first cladding is confined within a range of the core part and the first cladding, restricting a leakage thereof to the second cladding, and the propagation constant of each non-identical core is made different using the refractive index of the first cladding as a parameter.
