Nonlinear Fiber Bragg Gratings
In this paper we review some of the dominant topics in fiber Bragg gratings (FBGs). The combination of theory and simulations shows that these structures can use in filters, nonlinear fiber optical applications, soliton propagations etc. We discussed the theory of FBGs, grating solitons, Bragg soliton generation in intrinsic media and birefringence effects in FBGs together with some numerical s...
متن کاملPulse Switching in Nonlinear Fiber Bragg Gratings
The influence of the Kerr-like nonlinearity in the switching characteristics of fiber Bragg gratings is studied. Two types of apodization profiles are considered: uniform and raisedcosine apodized gratings. The influence of the bit-rate and the wavelength detuning of the incident pulses in the nonlinear response of the grating is analyzed. The deterioration in the pulses caused by the nonlinear...
متن کاملOptimization of Bistability in Nonlinear Chalcogenide Fiber Bragg Grating for All Optical Switch and Memory Applications
We solve the coupled mode equations governing the chalcogenide nonlinear fiber Bragg gratings (FBGs) numerically, and obtain the bistability characteristics. The characteristics of the chalcogenide nonlinear FBGs such as: switching threshold intensity, bistability interval and on-off switching ratio are studied. The effects of FBG length and its third order nonlinear refractive index on FBG cha...
متن کاملNonlinear Switching of Optical Pulses in Fiber Bragg Gratings
We study numerically the nonlinear switching characteristics of optical pulses transmitted though fiber Bragg gratings. We consider both the uniform and phase-shifted gratings and compare their performance as a nonlinear switch. The nonlinear coupled-mode equations were solved numerically to obtain the pulse-switching characteristics. The steady-state behavior known to occur for continuous-wave...
متن کاملSimulation and Applications of Nonlinear Fiber Bragg Gratings
We have simulated the behaviors of nonlinear fiber Bragg gratings (FBGs). The generalized nonlinear equations governing these structures are solved by a method which uses a Fourier series procedure and a simple iterative method. All of the nonlinear effects are considered. Bragg soliton generation in intrinsic media and birefringence effects in FBGs are studied. We found that the first order di...
