Abstract

Recently, experimental characterizations of deployed multicore fibers (MCFs) with a standard cladding diameter (

$125~\mu $

m) have been intensively reported; however, there have been a limited number of theoretical works to elucidate inter-core crosstalk (XT) properties during the cabling and installation processes. In this letter, the effect of a correlation length on the XT behaviors in MCFs under deployed conditions is investigated on the basis of a coupled-power theory. Comparing the calculated results to the measured results, it is confirmed that the XT behaviors in deployed MCFs are mainly dominated by structural fluctuations (random fluctuations of the refractive index distribution or of the fiber geometry along the MCF) and that the correlation length is estimated to be on the order of millimeters.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
