    "abstract": "We propose a new method for generating photon pairs from coherent light using\npolarization-dependent two-photon absorption. We study the photon statistics of\ntwo orthogonally polarized modes by solving a master equation, and show that\nwhen we prepare a coherent state in one polarization mode, photon pairs are\ncreated in the other mode. The photon pairs have the same frequency as that of\nthe incident light.",
