Paper Abstract

Dispersion-compensating chirped fiber gratings provide a compact low-loss means of compensating fiber dispersion. They are potential candidates for per-channel tunable dispersion compensation devices [2]. Group delay ripple (GDR) is the principle reason restraining the practical implementation of chirped fiber Bragg gratings and many papers indicate how the GDR impairs the systems performance [1, 3, 4]. S.Jamal has indicated that the period of the group delay ripple has much important influence on the systems performance [1]. But the ripple period of the chirped fiber grating was not consistent along side the grating, and Michael Sumetsky has explained the cutoff phenomenon of the high frequency in [2]. Because the period of the chirped fiber grating changed with the wavelength and the components of different frequency overlapped with each other, the time-frequency analysis was needed to descript the time-frequency distribution of the GDR of the grating.
