Metallic diffraction gratings for robust beam splitting

This paper designs and analyzes metallic diffraction gratings that act as reflective beam splitters, which could enable robust photonics applications. Using scalar and rigorous simulation methods, optimal grating parameters are found to cancel the zero-th diffraction order and achieve beam splitting for given metals, periods, polarizations and wavelengths. The dependence of required groove height on period and wavelength is also characterized.
