Abstract: A controllable electromagnetically induced grating (EIG) is experimentally realized in a coherent rubidium ensemble with 5S1/2-5P3/2-5D5/2 cascade configuration. In our work, a whole picture describing the relation between the first-order diffraction efficiency and the power… read more here.

DOI: 10.1364/ome.7.000366
Abstract: We propose quasi-periodic two-dimensional gratings comprised of a large number of circular holes for the high order diffraction suppression. By using Kirchhoff’s diffraction theory, we analytically investigate the diffraction property of the grating and optimize… read more here.
