Symmetric and asymmetric fiber loop mirrors for observing guided-acoustic-wave Brillouin scattering in polarization-maintaining fibers.
A new scheme of symmetric and asymmetric fiber loop mirrors is proposed to identify clearly the polarized guided-acoustic-wave Brillouin scattering spectra with multimode laser sources. The guided-acoustic-wave Brillouin scattering spectra in PANDA fibers in the low-frequency region are unambiguously confirmed with this scheme.
