“…If we assume a homogeneous 7-core TMF, which has a core at the center and six outer cores in a hexagonal layout, the electric fields in core A and B can be expressed as E A = A 01A (z)⋅E 01 (x,y) + A 11A (z)⋅E 11 (x,y) and E B = A 01B (z)⋅E 01 (x,y) + A 11B (z)⋅E 11 (x,y), respectively, where A µm is the amplitude of mode µ in core m, E µ is the transversal field distribution of mode µ in undisturbed fiber, and z is the propagation distance. Then, the inter-core mode couplings in a bent MC-TMF can be described as [13]…”

We analyze the inter-core crosstalk in homogeneous multi-core two-mode fibers (MC-TMFs) under bent condition by using the coupled-mode equations. In particular, we investigate the effects of the intra-core mode coupling on the inter-core crosstalk for two different types of MC-TMFs at various bending radii. The results show that the inter-core homo-mode crosstalk of LP(11) mode is dominant under the gentle fiber bending condition due to its large effective area. However, as the fiber bending becomes tight, the intra-core mode coupling is significantly enhanced and consequently makes all the inter-core crosstalk levels comparable to each other regardless of the mode. A similar tendency is observed at a reduced bending radius when the difference in the propagation constants between modes is large and core pitch is small.

“…One of the most important properties for signal transmission in MCF is controlling the inter-core crosstalk (XT). Coupled mode theory (CMT) has been emp loyed to estimate XT in various MCF [3,4]. Based on CMT, the power conversion efficiency oscillates sinusoidally in a homogeneous multicore fiber with two cores.…”
