Abstract :
The simulation model to bistable characteristics of grating is established by numerically solving the nonlinear coupled-mode equations of Fiber Bragg Grating using 3-stage 4-order semi-implicit Runge - Kutta method. The impact of the grating parameters and operating point on S-shaped hysteresis loop parameters is researched. The results show that the area of S-shaped hysteresis loop, bistable operating condition, bistable threshold and dynamic range can be adjusted by changing the operating wavelength and grating parameters, such as grating length, grating apodization and average refractive index modulation depth of grating.
