We report a detailed characterization of the properties of a chirped fiber Bragg grating with respect to the amount of applied chirp. The results demonstrate the reflection and dispersion dependencies associated with any linearly chirped grating. The dispersion of the device tested could be continuo

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
has been developed. Measurements were conducted at 470 and 900 MHz to conform to the frequencies used in industry. With the addition of a sleeve balun, measurement results show little difference with and without the hand touching the measuring cable at both frequencies. This shows that there is litt
Different schemes of dispersion compensation and the cascadability of chirped fiber gratings as dispersion compensators are in¨estigated. It is found that the coupling apodization profiles ha¨e great influences on the cascadability of the fiber gratings. In addition, we found that the optimal fiber
