title: Compact sources of polarization-entangled photons.
abstract: We present several novel sources of polarization-entangled states based on beam displacer interferometers. These sources generate a large number of high-quality entangled photon pairs in a compact alignment-free layout and can work with both cw and pulsed pumps.
