Stitch error effect on group-delay ripple for long chirped fiber Bragg gratings

Different sources of stitch errors are identified and simulated in a 200 mm long chirped grating. In each case, the effect on the group-delay ripple and transmission spectrum is investigated. The anticipated response in a typical 10 Gbit/s transmission system is specifically considered. From the simulations, it is clear that information about error source and magnitude can be gained directly from the transmission spectrum.
