M. Ibsen et al., Custom design of long chirped Bragg gratings: Application to gain-flattening filter with incorporated dispersion compensation, IEEE PHOTON, 12(5), 2000, pp. 498-500
We present and experimentally demonstrate simple relationships between the
refractive index modulation, the chirp-rate or dispersion and the transmiss
ion loss through, and reflection of, chirped Bragg gratings, and apply them
to the design of a new type of gain flattening filter with incorporated di
spersion compensation.
