摘要
We present a technique to measure the tensor components of the Raman gain spectrum in a short piece of optical fiber. Using this approach, we obtain results for the frequency dependence of the Raman gain tensor in a silica-based fiber for Raman shifts from less than 1 to over 15 THz. We compare these data with measurements of spontaneous Raman scattering in bulk silica and find good agreement for the depolarization ratio, including in the low-frequency regime.
