چکیده
In this paper, the coupled mode theory is used to analyze apodized fiber Bragg gratings (FBGs). Since the profile of gratings varies with the propagation distance, the coupled mode equations (CMEs) of apodized FBGs are solved by the fourth-order Runge-Kutta method (RKM) and piecewise-uniform approach (PUA). We present two discretization techniques of PUA to analyze the apodization profile of gratings. A uniform profile FBG can be expressed as a system Corresponding author: H.-W.

متن کاملDispersion Compensation Using Tunable Chirped Apodized Far Off Resonance Fiber Bragg Gratings in Transmission
Comparison between the results of strain and temperature dependent center Bragg wavelength shift have been accomplished using different apodization profiles to produce linearly chirped apodized far off resonance fiber Bragg gratings for the design of an optimum Dispersion compensator. The chirping is made using the ultraviolet (UV) phase mask method.
متن کاملReconstruction of fiber grating refractive-index profiles from complex bragg reflection spectra.
Reconstruction of the refractive-index profiles of fiber gratings from their complex Bragg reflection spectra is experimentally demonstrated. The amplitude and phase of the complex reflection spectrum were measured with a balanced Michelson interferometer. By integrating the coupled-mode equations, we built the relationship between the complex coupling coefficient and the complex reflection spe...

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 کاملA New Look at Numerical Analysis of Uni- Form Fiber Bragg Gratings Using Coupled Mode Theory
The coupled mode theory (CMT) is used to analyze uniform Fiber Bragg gratings. The multi-mode CMT is expressed as the first-order vector ordinary differential equations (ODEs) with coefficients depending on the propagation distance. We show in this paper that by changing variables, the original couple mode equations (CMEs) can be re-casted as constant coefficient ODEs. The eigenvalue and eigenv...
