| Abstract | The apodization function plays an important role in the behavior of the mean dispersion, group delay and significant reduction of sidelobe level in reflection spectrum. On the other hand, the grating length represents as one of the critical parameters in contributing to a high performance fiber Bragg grating compensator. In this paper, we have investigated and compared the performances of various apodization functions in linearly chirped apodized fiber Bragg grating. Six different apodization profiles have been studied including their effects on the performances of the dispersion compensator. Comparison reveals that the sinc profile results best performance for chromatic dispersion compensation. Simulations have been performed for sinc profile with different grating lengths. The simulated results were then analyzed by calculating the reflection spectrum. It is observed that the reflection spectrum becomes constant at a grating length of 10 cm. |
