| Multi-core fibers (MCFs), through the technique of space-division multiplexing (SDM), are the new type of fibers that promise to overcome the critical transmission capacity barriers and boost the capability of optical fiber communication (OFC) systems. However, when a MCF is considered as a medium for SDM transmission, the linear coupling between the MCF cores is a key feature to be considered and analyzed. The fundamental effects of the linear coupling on the nonlinear mechanisms of light-matter interaction that happen when an optical signal propagates through the MCF cores are still unexamined. This feature is actually the most important problem in MCFs, which promise high technological developments in OFC systems. In this thesis, we revisit and extend the single-core fiber (SCF) fundamentals and limits (the guided modes characteristics, nonlinear phase shift, nonlinear phase noise, self-phase modulation (SPM), and the size effects of the fiber cores) to a nonlinear directional fiber coupler (NLDFC), as the simplest MCF, described as a collection of two coupled SCFs. We present the results of a theoretical study of the effect of linear coupling on the nonlinear phase shift and frequency spectrum of an initial unchirped optical pulse propagating through a NLDFC, including the situation when the incoming signal is noisy. We focus on a NLDFC, which is the simplest, but most important, setup of MCFs to obtain physical insight of the effect of linear coupling on the phenomenon of SPM and nonlinear phase noise. For our purposes, the analysis of the elementary switching process in a NLDFC was suffice to obtain considerable and comprehensive results. | |
