Abstract:
We address the generation of entangled photon pairs by parametric downconversion from solid state
cw lasers with small coherence time. We consider a compact and low-cost setup based on a two-crystal
scheme with type-I phase matching.We reconstruct the full density matrix by quantum tomography and
analyze in detail the entanglement properties of the generated state as a function of the crystal’s length
and the coherence time of the pump.We verify the possibility to improve the visibility using a purification
protocol based on a compensation crystal
