Abstract

We use two perpendicular crystals of periodically-poled KTP to directly generate polarization-entangled photon pairs, the majority of which are emitted into a single Gaussian spatial mode. The signal and idler photons have wavelengths of 810 nm and 1550 nm, respectively, and the photon-pair generation rate is 1.2 × 10⁷ sec^-1 for a pump power of 62 mW. The apparatus is compact, flexible, and easily to use.
