Nonlinear Pulse Propagation in a Weakly Birefringent Optical Fiber Part 1: Deriva- Tion of Coupled Nonlinear Schrodinger Equations (cnlse)
نویسندگان
چکیده
A systematic derivation of the Coupled Nonlinear Schrodinger Equations (CNLSE) governing nonlinear pulse propagation in a weakly birefringent monomode optical fiber based on a multiple-scale perturbation solution of the semilinear vector wave equation for the electric field in a (randomly) birefringent fiber medium is presented. The analysis of the nonlinear propagation characteristics of optical pulses based on a numerical solution of the CNLSE is deferred to the second part of this contribution.

متن کاملNonlinear pulse propagation in birefringent fiber Bragg gratings.
We present two sets of equations to describe nonlinear pulse propagation in a birefringent fiber Bragg grating. The first set uses a coupled-mode formalism to describe light in or near the photonic band gap of the grating. The second set is a pair of coupled nonlinear Schroedinger equations. We use these equations to examine viable switching experiments in the presence of birefringence. We show...
متن کاملPolarization mode interaction equations in optical fibers with Kerr effect
We derive coupled nonlinear Schrödinger equation (CNLSE) for arbitrary polarized light propagation in single-mode fiber. Considering a weak nonlinearity which is connected with Kerr effect, we give explicit expressions for nonlinear constants via integrals of Bessel functions. The method of projecting we use allows a direct generalization to multi-mode fiber case.

A system of coupled nonlinear Schrödinger equations describes pulse propagation in weakly birefringent optical fibers. Soliton solutions of this system are found numerically through the shooting method. We employ Poincaré surface of section plots—a standard dynamical systems approach—to analyze the phase space behavior of these solutions and neighboring trajectories. Chaotic behavior around the...
متن کاملSoliton stability in birefringent optical fibers : analytical approach
Propagation of short pulses in birefringent optical fibers is considered in the framework of two coupled nonlinear Schr8dinger equations. When the amplitudes of the pulses belonging to different polarizations are equal, we propose a simple analytical explanation of the amplitude threshold for the capture of two partial pulses into a coupled two-component pulse. Our approach is based on a solito...
