Diffraction of quasimonochromatic light beams on multilayer inhomogeneous photopolymer holographic diffraction structures

Abstract

A theoretical model of quasimonochromatic light beams diffraction by spatially inhomogeneous transmitting multilayer diffraction structures formed in a photopolymer material by a holographic method is presented in this work. This model takes into account the heterogeneity of the amplitude profile of the first harmonic of the refractive index of each layer of the multilayer structure. The model is presented using method of transfer matrixes whose components are the solutions of the coupled waves equations of partial derivates.

Studying the process of holographic formation of multilayer inhomogeneous PPM-LC diffraction structures

“…The response is characterized by a number of local maxima, which number and width is defined by the thicknesses of the holograms and buffer layers. In this case the envelope of the selectivity contour coincides with the selectivity contour of single holograms [3,5]. These properties of such multilayer structures can have the potential of finding application in components of optical devices, for example, in spectral filters, sensors, interconnections, and femtosecond laser optics, along with the prospect of application in communication equipment, which in turn can lead to development of a new element base in fiber optics.…”

“…The unique properties of multilayer inhomogeneous holographic diffraction structures, caused by the interaction of optical radiation during their formation and diffraction of light on them, are being investigated by a number of scientists from different countries of the world [1][2][3][4][5][6][7]. Due to interference effects occurring between diffraction layers separated by an intermediate buffer layer, a complex type of selective response of optical emission can be observed at the output of this structure.…”

“…We assume that the refractive index of the intermediate layer is equal to the refractive index of the hologram. Then the transition matrix , nm A it will look like [5][6][7]:…”

“…In the last few years, various teams of researchers from different countries have been studying multilayer inhomogeneous holographic diffraction structures (MIHDS) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. MIHDS are several volumetric lattices separated by optically homogeneous intermediate layers [1][2][3][4].…”
