Generation of polarization-entangled photon pairs in a Bragg reflection waveguide

Abstract:

We demonstrate experimentally that spontaneous parametric down-conversion in an AlxGa1-xAs semiconductor Bragg reflection waveguide can make for paired photons highly entangled in the polarization degree of freedom at the telecommunication wavelength of 1550 nm. The pairs of photons show visibility higher than 90% in several polarization bases and violate a Clauser-Horne-Shimony-Holt Bell-like inequality by more than 3 standard deviations. This represents a significant step toward the realization of efficient and versatile self pumped sources of entangled photon pairs on-chip. © 2013 Optical Society of America.
