Optical Properties of Chromium and Erbium Co-Doped Alumina–Germania–Calcia–Yttria–Silica Based Fiber

description We report the fabrication details and optical characterization of novel Erbium (Er) and Chromium (Cr) co-doped alumina-germania-calcia-yttria-silica fiber. Co-doping with Er and Cr is chosen as potentially promising for enhancing the fiber&#x0027;s fluorescent and amplifying potential in the near-infrared (NIR) region at &#x2018;resonant&#x2019; (viz. into Er band absorption maximum, &#x0040;976&#x00A0;nm) and &#x2018;non-resonant&#x2019; (viz. off Er band while into Cr broad absorption band, &#x0040;905&#x002F;1064 nm) excitations. Our results reveal strong coupling, at both kinds of excitation, of Er- and Cr- subsystems in the fiber. This effect is justified by the presence of pronounced 1.5&#x2013;1.6&#x00A0;&#x03BC;m emission, characteristic to Er ions, at 905&#x002F;1064&#x00A0;nm excitations and, at 976-nm excitation, by notable spectral broadening of the fiber&#x0027;s NIR fluorescence and gain, comprising the lines inherent to Er<sup>3&#x002B;</sup> (1.5&#x2013;1.6&#x00A0;&#x03BC;m) and Cr<sup>3&#x002B;</sup>&#x002F;Cr<sup>4&#x002B;</sup> (1.15&#x2013;1.45&#x00A0;&#x03BC;m), as compared to purely Er-doped silicate fiber, exemplified here by commercial &#x2018;L20&#x2019; (Er20-4&#x002F;125) and &#x2018;L40&#x2019; (Er40-4&#x002F;125) fibers.
