We report a simple and practical approach for generating high-quality polarization entanglement in a fully guided-wave fashion. Both deterministic pair separation into two adjacent telecommunication channels and the paired photons' temporal walk-off compensation are achieved using standard fiber components. Two-photon interference experiments are performed, both for quantitatively demonstrating the relevance of our approach and for manipulating the produced state between bosonic and fermionic symmetries. The compactness, versatility and reliability of this configuration makes it a potential candidate for quantum communication applications.
