Abstract
The relationship between group-delay ripple and the apodization profile of chirped Bragg gratings is analyzed. Simple physical explanations are given for departures from ideal linear group delay by use of only the concepts of reflection at discontinuities and band gaps and the optical path lengths o f cavities. Quantitative expressions are obtained for the amplitudes, phase s, and periods of both the fast and slow components of the ripple. (C) 2000 Optical Society of America.
