We report type II sum-frequency and second-harmonic generation in a 24-cm-long periodically-poled silica fiber. Quasi-phase matching is achieved for orthogonally-polarized signal and idler over 1520-1575 nm, demonstrating the path to in-fiber broadband polarization-entangled photon pair generation.
