    摘要: A multicore optical fiber that includes a plurality of waveguiding cores disposed in a cladding. The plurality of waveguiding cores include one or more first waveguiding cores that have a first propagation constant and one or more second waveguiding cores that have a second propagation constant, where the first propagation constant differs from the second propagation constant. The one or more first waveguiding cores and the one or more second waveguiding cores are disposed in the cladding in a ring distribution and at least a portion of the ring distribution is arranged based on a quasi-periodic sequence having a plurality of sequence segments. Each sequence segment is determined based on a quasi-periodic function, has an order, and corresponds to an arrangement segment of a first waveguiding cores, a second waveguiding cores, or combinations thereof. The ring distribution includes at least one arrangement segment corresponding with a third-order sequence segment or higher of the quasi-periodic sequence.

    摘要: A hollow glass waveguide and related method are provided. The microwave waveguide includes a glass body including a first end, a second end, an outer glass surface extending between the first end and the second end, an inner glass surface defining a hollow channel that extends from the first end to the second end and a glass material between the outer surface and the inner surface. The microwave waveguide includes a layer of metal embedded in the glass body. The layer of metal surrounds the hollow channel when viewed in cross-section and extends between the first end and the second end of the glass body. The layer of metal is electrically conductive and the hollow channel is dimensioned such that microwaves introduced into the hollow channel are conducted along the hollow channel between the first end and the second end.
