Mitigating the Brillouin strain and temperature cross-sensitivity in heavily GeO2-doped-core optical fibers

We demonstrate an athermal Brillouin strain sensor using heavily GeO2-doped optical fibers. We also report nonlinear evolution of Brillouin temperature sensitivity as a function of wavelength and strong Brillouin gain in these fibers.
