On the group delay characteristics of chirped fibre Bragg gratings
Abstract
It is shown for the first time that the group delay characteristics of chirped fibre Bragg gratings show a symmetry when measured from either direction. It is shown that the dispersion of a chirped grating cannot be completely compensated by another identical grating. This has implications on the quality of apodisation required for dispersion compensation.
