Euclidian Distance Method for Optimizing Linearly Chirped Fiber Bragg Grating Apodization Profile

In this paper, we use Euclidian distance method to solve the tradeoff between Group delay Ripple (GDR) and Full Width Half Maximum (FWHM) Bandwidth. This method determines the optimum point by maximizing FWHM spectral bandwidth and minimizing GDR based on the value of sharpness parameters α and β. Three different apodization profiles were used to evaluate this method. The study shows that the best α and β is 16 and 2.25 respectively. The apodization profile that was optimized the most by this method is Tanh
