Abstract
In this paper, a new design of seven-core hole-assisted multi-core fiber with surrounding each core is presented. Here, the holes are assumed to be filled with materials having very low refractive index contrast with cladding. Coupling of light from the central core to the outer cores of seven-core structure is investigated by rotating the holes in the range +30° to −30° around the central core. The optimum range of angles for which coupling is very low is estimated for different values of core-pitch. An average value of crosstalk and power penalty are then calculated from the minimum coupling region for core pitch
$40~\mu \text{m}$
to
$45~\mu \text{m}$
where crosstalk goes below the threshold limit (which is taken as −30dB). An analytical model has also been developed based on proposed design and the results are seen to be in good agreement with the results from simulation. The proposed optimum design is extremely helpful for enhancing the capacity and efficiency of Space division multiplexing based applications with low crosstalk and power penalty.
期刊介绍:
The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
