Sukhorukov, "Photon-pair generation via bound states in the continuum in nonlinear metasurfaces," in 14th Pacific Rim Conference on Lasers and Electro-Optics (CLEO PR 2020), OSA Technical Digest (Optica Publishing Group, 2020), paper C8G_2. https://opg.optica.org/abstract.cfm?URI=CLEOPR-2020-C8G_2978-0-646-82504-5http://hdl.handle.net/1885/274491We present a novel nonlinear metasurface featuring reconfigurable symmetry protected bound states in the continuum. It enhances photon-pair generation at non-degenerate photon frequencies via spontaneous parametric down-conversion, opening new opportunities for quantum spectroscopy and sensing.application/pdfen-AU© 2020 OSA202010.1364/CLEOPR.2020.C8G_22023-01-15
