Abstract

A spatially resolved Raman study of self-organized χ(2) gratings in optical fibers shows a periodic modulation in the strength of the low-frequency (ν ≤ 600 cm−1) Raman spectrum. In a fused-silica fiber the measured period ranges from 27 to 50 μm, and the modulation amplitude is ±3% of the average Raman signal.

Fig. 1
Fig. 1

Average of 24 spectra recorded with 2-μm steps. Vertical scale is linear with a peak signal of ~6 counts/sec; the baseline, which is shifted up for the erased fiber, is zero.

Fig. 2
Fig. 2

Average Raman signal in the 210–500-cm−1 region as a function of the relative position along the fiber for (a) a conditioned fiber and (b) the same fiber with the grating erased. Each spectrum was normalized with respect to the 820-cm−1 band.

Fig. 3

Spectra from the run shown in Fig. 2(a) corresponding to relative fiber positions of 15 μm (the lower curve) and 33 μm (the upper curve).
