Optically active defects in silica have been studied for decades and are often indicators of network irregularities such as those that might result from optical or mechanical damage. They are well-known to be weak emitters and are usually present in

The doping of dielectric nanoparticles (NPs) into the cores of silica fibers doped with a rare earth (RE) has proven to be an effective approach for controlling the spectroscopic performance of the rare earth. However, little is understood about the

A silica clad optical fiber with a core comprised of SiO2, P2O5, Al2O3, and AlPO4 is analyzed in order to determine the impact of AlPO4 when added to silica. A chromatic dispersion curve is presented, from which the nonlinear refractive index is esti

A method, based on Brillouin scattering, to evaluate the quantum conversion efficiency (QCE) in Yb-doped optical fibers is designed and tested. An adapted version of the heterodyne approach to measuring the Brillouin spectrum is first used to precise

The first observation of cooling by anti-Stokes pumping in nanoparticle-doped silica fibers is reported. Four Yb-doped fibers fabricated using conventional modified chemical vapor deposition (MCVD) techniques were evaluated, namely, an aluminosilicat
