Researchers observed near-ideal interference fringe visibilities of up to 99.9% (blue curve).
Joseph M. Lukens, Nicholas A. Peters, and Raphael C. Pooser's forth-coming article in Optics Letters, "Naturally stable Sagnac–Michelson nonlinear interferometer" has earned an "Editor's Pick" to promote it for its high technical quality and its expected interest to the scientific community.
