Interference effect of coherent transmittance quenching: theoretical study of optical modulation by surface ferroelectric liquid crystal droplets

Abstract: Within the framework of the single scattering and the anomalous diffraction approach, the conditions for coherent transmittance quenching for surface ferroelectric liquid crystal (SFLC) droplets have been found. The influence of the droplet polydispersity and the disorientation of their optical axes for the SFLC film for the conditions under which the film coherent transmittance becomes zero is analysed. The contrast ratio and the modulation depth of the SFLC film under the conditions of coherent transmission … Show more

“…It is based on the amplitude-phase screen model, interference approximation of multiple wave scattering [9,16,17], and anomalous diffraction approximation to describe scattering of radiation by a single droplet. Numerical analysis of coherent transmission coefficients and scattered intensities were performed for monolayers of spherical droplets of nematic liquid crystals with inhomogeneous boundary conditions [18][19][20].…”
