Abstract

The performances of various apodization profiles, namely Gaussian, raised sine and hamming function for unchirped fiber Bragg grating are presented. The performances investigated include reflectivity, full width half maximum bandwidth, and sidelobe level. Transfer matrix method was adopted to solve the coupled mode equation to simulate the spectral profile of the apodized fiber Bragg gratings. The apodization performances were investigated under various refractive index modulation values and various grating length values. The results show that Gaussian profile suppresses sidelobe level much more efficiently than raised sine and hamming function.
