Investigation of multiple Bragg reflections at a constant neutron wavelength and their possible separation
Multiple Bragg reflections (MBR) realized in one bent-perfect crystal (BPC) slab by sets of different lattice planes behave differently in comparison to the case of perfect nondeformed or mosaic crystal. Individual sets of lattice p...

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