Based on linear-system theory, a method to obtain the total group-delay characteristics of the cascaded chirped fiber Bragg grating (FBG) from the measured group delays of each grating is proposed. The method is then used to characterize cascaded chirped FBGs used as the dispersion compensators of a
## Abstract A new technique for inducing relative group delays between the orthogonal transversal propagation modes in a single mode fiber is presented. It is based on a tunable linear chirp induced in a Bragg grating written in a highly birefringent fiber by thermal means. The method can induce a
## Abstract A polarimetric method was used to measure the differential group delay and ripple of chirped Bragg gratings. The results were compared to the phaseβshift technique and it was verified that the polarimetric method does not suffer the resolution limitations inherent to the modulation phas
