摘要: We report the experimental generation of polarization-entangled photons at telecommunication wavelengths using spontaneous four-wave mixing in silicon-on-insulator wire waveguides. The key component is a 2D coupler that transforms path entanglement into polarization output device. Using quantum state tomography we find produced has fidelity 88% with pure nonmaximally entangled state. violates CHSH Bell inequality by S=2.37±0.19.
