N. Roussel et al., Measurement of index modulation along fiber Bragg gratings by side scattering and local heating techniques, OPT FIBER T, 5(1), 1999, pp. 119-132
A method for measurement of index modulation profile along fiber Bragg grat
ings is described which uses a hot finger that selectively heats some fring
es. Results obtained from this local heating technique and side scattering
technique are reviewed and compared. (C) 1999 Academic Press.
