TL;DR: In this article, the coupling coefficient between multiple modes under periodic perturbation conditions for hexagonal seven core configuration was studied and a complete view for fundamental modes for each core and other linearly polarized modes were obtained.
Abstract: This paper presents a study on the propagation of modes of electromagnetic wave through a homogeneous multicore fiber. Complete view for fundamental modes for each core and other linearly polarized modes are obtaining here. Coupling between fundamental modes and other different cladding modes are presented in this paper. This study includes the coupling coefficient between multiple modes under periodic perturbation conditions for hexagonal seven core configuration.

TL;DR: In this article, a hole-walled six core fiber (MCF) structure is introduced and first three LP core modes (LP 01, LP 11 a and LP 11 b) are studied.
Abstract: To meet the growing demand for communication channel capacity, various types of space division multiplexing (SDM) transmission fiber have been proposed. In this paper, a novel hole-walled six core fiber (MCF) structure is introduce and first three LP core modes (LP 01 , LP 11 a and LP 11 b) modes are studied. These two modes are very important for long distance optical fiber communication. Some supported higher order cladding modes are also presented and very peculiar field distributions can be found. Results are compared with normal step-index six core MCF structure. It is found that cladding modes can be greatly suppressed with hole-walled structure. This study also includes the coupling between LP 01 mode and one higher order cladding mode under periodic perturbation conditions.

TL;DR: In this article, a special type of homogeneous multicore fiber structure is introduced and the array of holes is placed between each core, and the normalized propagation constant, mode field diameter (MFD) of LP 01 mode of this structure are studied.
Abstract: The need for the enhancement of channel capacity of optical fiber, space division multiplexing (SDM) transmission fibers- such as the multicore fiber, the multimode fiber and the few-mode multicore fiber, etc., - have been researched for long-distance communication system. In this paper, a special type of homogeneous multicore fiber structure is introduced and the array of holes is placed between each core. The normalized propagation constant, mode field diameter (MFD) of LP 01 mode of this structure are studied here. The empirical relation between normalized propagation constant and V number of LP 01 mode of a single core single-mode fiber is compared with simulation results of LP 01 mode of a multicore fiber. The mode field diameter of MCF is derived by noting the beam radius where the intensity drops to 1/e2 of the intensity on the beam axis. The theoretical prediction match well with COMSOL results. These results are useful for the investigation of the detailed characteristics of different types of MCF.

TL;DR: In this article , a novel twelve core fiber (MCF) double layer hexagonal shape design with an air-hole between the cores is proposed and couplings between core modes and cladding mode are studied.
Abstract: To support the rapid traffic growth, space division multiplexing (SDM) transmission technology have been introduced to overcome the ‘capacity crunch’. In this paper, a novel twelve core fiber (MCF) double layer hexagonal shape design with an air-hole between the cores is proposed and couplings between core modes and cladding mode are studied. Fundamental modes distribution of 12 core is presented. Results are compared with normal step-index twelve core MCF structure. It is found that cladding modes can be greatly suppressed with air hole between the cores. This study also includes the coupling between LP01 mode and one higher order cladding mode under periodic perturbation conditions.
