| Abstract: | The design criteria for fibre Bragg grating dispersion compensation are discussed, and the use of local grating dispersion
d2 φ/d2 by Bennion et al. 1] is shown to be overly restrictive. A more useful measure of compensation degradation is phase
deviation from the desired quadratic frequency dependence.
