| description | The correlation and power distribution of intercore crosstalk (ICXT) field components of weakly coupled multicore fibers (WC-MCFs) are important properties that determine the statistics of the ICXT and ultimately impact the performance of WC-MCF optical communication systems. Using intensive numerical simulation of the coupled mode equations describing ICXT of a single-mode WC-MCF with intracore birefringence and linear propagation, we assess the mean, correlation, and power distribution of the four ICXT field components of unmodulated polarization-coupled homogeneous and quasi-homogeneous WC-MCFs with a single interfering core in a wide range of birefringence conditions and power distribution among the field components at the interfering core input. It is shown that, for homogeneous and quasi-homogeneous WC-MCFs, zero mean uncorrelated ICXT field components with similar power levels are observed for birefringence correlation length and birefringence beat length in the ranges of <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mfenced separators="" open="[" close="]"><mn>0.5</mn><mspace width="0.277778em"></mspace><mi mathvariant="normal">m</mi><mo>,</mo><mn>10</mn><mspace width="0.277778em"></mspace><mi mathvariant="normal">m</mi></mfenced></semantics></math></inline-formula> and <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mfenced separators="" open="[" close="]"><mn>0.1</mn><mspace width="0.277778em"></mspace><mi mathvariant="normal">m</mi><mo>,</mo><mn>10</mn><mspace width="0.277778em"></mspace><mi mathvariant="normal">m</mi></mfenced></semantics></math></inline-formula>, respectively, regardless of the distribution of power between the four field components at the interfering core input. |
