The concept is developed from basic physical considerations to provide asymmetric coupling between harmonic wave components of the electromagnetic field. The structure results in a nonreciprocal chirality and asymmetric transmission between in- and out-coupling channels into the structure. The analytical results are supported by a numerical study of the Bloch-like mode formations and calculations of a realistic planar semiconductor structure. © 2015 American Physical Society.EnglishElectromagnetic fieldsAnalytical resultsAsymmetric couplingAsymmetric transmissionsCoupling channelsMode formationNonreciprocalPhotonic structurePlanar semiconductorsEigenvalues and eigenfunctionsArticle10.1103/PhysRevA.91.0238252469-9934
