  • Abstract
    This paper tackles the Polarization Dependence of Gain (PDG) in distributed Raman amplifier (DRA) system with orthogonal polarization multiplexed pump lights. We show that polarization mode dispersion in transmission line degrades the orthogonality of pump lights and induces PDG. We propose a compact pump depolarizer to suppress PDG.
