Abstract
Coupled-wave analysis is used to design binary gratings with high efficiencies (70-80%). The binary designs have grating periods greater than one wavelength but use subwavelength structures within each period in order to achieve high efficiency.Year: 1992 PMID： 20725441 DOI： 10.1364/AO.31.004453
