Abstract
Neutron low-index thin-film waveguides and waveguide coupler with anti resonant high-reflection layers are proposed and realized experimental ly. In contrast to the conventional thin-film waveguides, neutrons are confined in a region with a refractive index lower than those of the neighboring media. As shown, the in/out coupling of resonant modes is realized by the conventional neutron-reflectometry technique. Original numerical methods are used to evaluate the eigenstates.
