Hello!
I try to do simulations with OptiGrating and OptiSystem, try to make a chirped fiber bragg grating (CFBG).
I have a few questions, please try to help me:
1) Where i could find mathematical equations for calculating chirped FBG (because i try to compare mathematical model with simulation model and then implement it experimentally) for ex. where i could find the math algorithms and equations that are used in OptiGrating to calculate phase, reflection spectrum, time delay, chirp coefficient
2) when i try to simulate CFBG in OptiGrating, for example with this parametrs (Lg=0.4m, low wavelength= 1547.5 nm, step 1nm, high wavelength 1550.5, mean group delay 835 ps/nm, chirp coefficient i dont know exactly) i am failed.
Thank you a lot.
