GeO2-core/SiO2-cladding optical fibers (GESI fibers) and liquid core fibers with a cladding region of GeO2 were designed and fabricated by the MCVD process. The attenuation level of the GESI fibers was about 0.5 dB/m in the near-infrared wavelength region at 2.35 μm. GESI fibers showed a stimulated Raman scattering (SRS_ spectrum with six to seven Stokes shifts of 430 cm−1. The spectrum of SRS expanded to 1.6 μm when a Nd: YAG laser at a wavelength of 1.064 μm was used.
