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

      Valles Marin, Adam; Hendrych, M.; Svozilik, Jiri; Machulka, R.; Abolghasem, P.; Kang, D.; Bijlani, B.J.; Helmy, A.S.; Pérez Torres, Juan (2013-06)
      Article
      Accés obert
      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 ...

    • Hyperentangled photon sources in semiconductor waveguides 

      Kang, D.; Helt, L. G.; Zhukovsky, Sergei V.; Pérez Torres, Juan; Sipe, J. E.; Helmy, A.S. (2014-02-19)
      Article
      Accés obert
      We propose and analyze the performance of a technique to generate mode and polarization hyperentangled photons in monolithic semiconductor waveguides using two concurrent type-II spontaneous parametric down-conversion ...
