| Abstract: | The time delay characteristics of non_uniform optical fiber gratings with different types of apodising and chirping structure are analyzed using numerical method. For understanding and designing fiber gratings we defined apodization profile functions and calculated numerically. The influence of apodization profile functions,the variation of the induced index and chirp parameter on the dispersion compensation,the time delay characteristics and the bandwidth has been studied. |
