Crosstalk analysis in homogeneous multi-core two-mode fiber under bent condition. J. H. Chang, H. G. Choi, S. H. Bae, D. H. Sim, Hoon Kim, & Y. C. Chung Optics Express, 23(8):9649–9657, April, 2015. ![Crosstalk analysis in homogeneous multi-core two-mode fiber under bent condition [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex 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 LP11 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.
