Abstract :
The present research work provides a very simple analytical analysis of optical switching and transistor characteristics of nonlinear fiber Bragg grating. The nonlinear coupled mode equations have been solved to analyze the wave propagation in grating that exhibit attractive nonlinear optical property that makes them suitable for all-optical communication system. We derived the solutions for both forward and backward propagating field amplitudes considering the propagation of a high intense beam. Using the expression of reflectivity derived under nonlinear regime we examine the nonlinear switching and optical transistor behavior of fiber Bragg grating. We also obtained the expression for peak reflectivity of the grating under nonlinear Kerr regime. Using these expressions we have studied the peak reflectivity as a function of grating length at different input intensities.
