Abstract: In this paper, we report the successful realization of c-band operable FBG-based Gires-Tournois etalon dispersion compensations where the dispersion tuning range has been more than doubled by the inclusion of an additional etalon. This results in a compact tunable dispersion compensator, which has the advantages of multi-channel operation, extremely low group delay ripple, and low cost. [Copyright &y& Elsevier]

We present an optimization process for the apodization strength factor of fiber Bragg grating dispersion compensators. It will he demonstrated that a proper choice of the apodization strength factor results in minimum deviation of the dispersion from the required level, maximum reflection bandwidth and minimum group delay ripple impact, thus leading to a reduction of the Q-factor penalty of the dispersion compensating system. We also discuss the influence of the fiber link length in the determination of the optimum apodization strength factor, taking into account that shorter links minimize the group delay ripple amplitude, whereas the longer ones maximize the bandwidth of interest. It is determined that a fiber link length of ∼80 km can balance the requirements of group delay ripple impact and bandwidth. The results obtained through this analysis allow a faster modeling of the Bragg grating parameters in order to achieve an improved spectral performance, as well as a cost-effective fabrication process.
