    "abstract": "We experimentally investigate a double-pass parametric down-conversion scheme\nfor producing pulsed, polarization-entangled photon pairs with high visibility.\nThe amplitudes for creating photon pairs on each pass interfere to compensate\nfor distinguishing characteristics that normally degrade two-photon visibility.\nThe result is a high-flux source of polarization-entangled photon pulses that\ndoes not require spectral filtering. We observe quantum interference visibility\nof over 95% without the use of spectral filters for 200 femtosecond pulses, and\nup to 98.1% with 5 nm bandwidth filters.",
