Apodized fiber Bragg gratings with greater than or equal to 30-dB side
lobe suppression +/-1 nn from the Bragg center wavelength are spatiall
y characterized with side-scatter and side-diffraction techniques. Res
onant side scatter is suppressed, indicating that little dispersion ar
ises from reflections off the grating boundaries. (C) 1997 Optical Soc
