Generation of photon pairs using polarization-dependent two-photon absorption
Toshihiro Nakanishi, K. Sugiyama, Masao Kitano · Physical Review A · 2003
We propose a method for generating photon pairs from coherent light, using polarization-dependent two-photon absorption. We study the photon statistics of two orthogonally polarized modes by solving a master equation, and show that when we prepare a coherent state in one polarization mode, photon pairs are created in the other mode. The photon pairs have the same frequency as that of the incident light.
