Abstract

Analytical expressions for the output pulse broadening and eye‐diagram power penalty of a chirped sampled Bragg grating (CSBG) dispersion compensator are derived. The result is applied to optimize the design of residue dispersion ratio in each channel and the total channel number of a fixed‐length CSBG. The optimal residue dispersion ratio does not change when the channel number changes. The filter‐induced pulse distortion will induce an additional eye‐diagram power penalty and will give an upper limit for the channel number of 40‐G+ systems. © 2002 Wiley Periodicals, Inc.

The optimum design for a 10-Gb / s NRZ chirped fiber grating dispersion-compensated system operating at 1.55 m over standard fiber is investigated. The study considers self-phase modulation, dispersion, modulator chirp, and amplifier noise. Transmission over 1700 km of fiber may be achieved by incor

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

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

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
