Influence of buffer layer and grating layer on diffraction of multilayer volume holographic grating

Research of light diffraction on multilayer PPM-LC diffraction structures under conditions of external electrical influence

“…-surface adhesion parameter, α W -azimuthal surface coupling coefficient, Δε -dielectric anisotropy of the bipolar capsule. Critical electric field strength the photoinduced Fredericks transition, in which the rotation of the LC director occurs, is defined as [4]:…”

“…The interaction of light fields of the 0th and 1st diffraction orders in the nth layer of the MIHDS is solved by the matrix method in the form of [4,5]:…”

“…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]. Such structures are characterized by special properties due to the interference of waves from each lattice [1].…”
