| Abstract: | The responses of non uniform optical fiber gratings with different types of apodising and chirping structure are analyzed using matrix method .For understanding and designing fiber gratings we defined apodization profile functions and calculated numerically. We found that the optimal apodization profile is the raised cosine shape. |
