Abstract

We report theoretical and experimental analysis on Brillouin frequency shift in silica optical fibers with the double cladding structures that are comprised of GeO2-doped core, P2O5- and F-codoped inner cladding and silica outer cladding. The intrinsic Brillouin frequency shift was calculated for various fiber parameters utilizing boundary conditions for longitudinal acoustic waves. Optical fibers with different fiber parameters were fabricated and the Brillouin frequency shifts were measured in the wavelength region of 1.55μm. We confirmed that the inner cladding in an optical fiber could provide a new degree of freedom in controlling the Brillouin frequency shift.
