Incoherent phenomena in anisotropic periodic structures: from modeling to experimental demonstration

Popis výsledku v původním jazyce

The periodic structures are widely studied in numerous optical applications and thereis a number of good tools for numerical modeling of such a structures (for example RigorousCoupled-Wave Analysis, Finite-Difference Time-Domain, Finite Element Method etc.). However,when it comes to modeling of incoherent effects in many cases of practical interest, the currentmethods are not rigorous enough or depend on computationally demanding averaging of coherentresponse. In this paper, we present a novel approach to modeling of incoherent effects instructures with lateral periodicity based on scattering matrix formalism, as a way to describeoptical response of a structure, and on application of incoherent wave summation in the form ofinfinite geometric series and generalized Mueller matrix calculus. This method can be combinedwith any of existing coherent methods of modeling periodic structures and it offers significantlyfaster computational performance than partially coherent/incoherent methods based on averaging.It is compared with other methods for modeling of incoherent effects and also with experimentalspectroscopic data. This method is then used to explain phenomena emerging from the complexinteraction between diffraction grating and thick substrate.
