A modal analysis of lamellar diffraction gratings in conical mountings
A rigorous modal analysis of lamellar gratings, i.e . gratings having rectangular grooves, in conical mountings is presented . It is an extension of the analysis of Botten et al . which considered non-conical mountings. A key step in the extension is a decomposition of the electromagnetic field in the grating region into two orthogonal components. A computer program implementing this extended m...
متن کاملFourier-matching pseudospectral modal method for diffraction gratings.
A Fourier-matching pseudospectral modal method [PSMM(f)] is developed for analyzing lamellar diffraction gratings or grating stacks. A Chebyshev pseudospectral method is first used to accurately calculate the eigenmodes of the grating layers, and then the Fourier coefficients are matched at the interfaces between the layers. Compared with an existing pseudospectral modal method based on point m...
متن کاملPseudospectral Modal Method for Conical Diffraction of Gratings
For lamellar gratings and other layered periodic structures, the modal methods (including both analytic and numerical ones) are often the most efficient, since they avoid the discretization of one spatial variable. The pseudospectral modal method (PSMM) previously developed for in-plane diffraction problems of one-dimensional gratings achieves high accuracy for a small number of discretization ...
متن کاملHigh Order Finite Difference Modal Method for Diffraction Gratings
A new high order finite difference modal method (FDMM) is developed for analyzing diffraction gratings in conical and classical mountings. The difference scheme is constructed by enforcing the internal interface conditions in each grating layer to high order derivatives, and it gives a high order of accuracy for computing the eigenmodes of the grating layer. Between different layers, the interf...
متن کاملDimensional changes in slanted diffraction gratings recorded in photopolymers
Photopolymers are appealing materials for many optical applications. For most of them, shrinkage plays an important role in the final properties of the display, especially in holographic data storage applications. In this paper, we demonstrate that to quantify correctly the shrinkage, it is mandatory to measure the angle of propagation for both diffracted orders ± 1, so that an accurate value o...
