Behavior of intercore crosstalk in square-layout uncoupled four-core fibers

چکیده
Recently, a very interesting behavior of crosstalk (XT) between diagonal cores (diagonal XT) in square-layout uncoupled four-core fiber (UC-4CF) that grows quadratically with length has been reported. In this paper, the intercore XT UC-4CFs is investigated on basis coupled-power theory. To make it easy to understand physical mechanism behavior, we derive an approximate solution equations. We show there exists range lengths within which quadratically. Finally, propose heterogeneous UC-4CF could be further suppressed.

Simple analytical expression for crosstalk estimation in homogeneous trench-assisted multi-core fibers.
An analytical expression for the mode coupling coefficient in homogeneous trench-assisted multi-core fibers is derived, which has a simple relationship with the one in normal step-index structures. The amount of inter-core crosstalk reduction (in dB) with trench-assisted structures compared to the one with normal step-index structures can then be written by a simple expression. Comparison with ...
متن کاملCrosstalk behavior of cores in multi-core fiber under bent condition
Measurement results of bending diameter dependence of the crosstalk of each core in a multi-core fiber are presented. The crosstalk of cores shows different diameter dependence although the difference in core parameters is very small. The behavior is explained by taking into account the change of propagation constant caused by the fluctuation in the diameter and the refractive index of cores. T...
متن کاملCrosstalk behavior of multi-core fiber with structural parameter drift in longitudinal direction
An impact of longitudinal structural parameter drift on crosstalk behavior of multi-core fibers is investigated with a newly proposed semi-analytical method which can easily simulate crosstalk under the various kinds of parameter drifts. The simulation results indicate that the structural parameter drift has an important role in moderating bending diameter dependence of crosstalk of multi-core ...
متن کاملIntermodal and cross-polarization four-wave mixing in large-core hybrid photonic crystal fibers.
Degenerate four-wave mixing is considered in large mode area hybrid photonic crystal fibers, combining photonic bandgap guidance and index guidance. Co- and orthogonally polarized pump, signal and idler fields are considered numerically by calculating the parametric gain and experimentally by spontaneous degenerate four-wave mixing. Intermodal and birefringence assisted intramodal phase matchin...
متن کاملRGB generation by four-wave mixing in small-core holey fibers
We report the generation of white light comprising red, green, and blue spectral bands from a frequency-doubled fiber laser in submicron-sized cores of microstructured holey fibers. Picosecond pulses of green light are launched into a single suspended core of a silica holey fiber where energy is transferred by an efficient four-wave mixing process into a red and blue sideband whose wavelengths ...
