Special Issue Information

Dear Colleagues,

This Special Issue, “New Advances in Modeling, Simulation, and Analysis of Optical Materials”, will address advances in numerical simulation, theoretical analysis, and characterization of optical materials. The impact of numerical simulation on different branches of science has seen a dramatic increase in the past decades. The rising of the computational power of modern CPUs and parallelism in both software and hardware has permitted facing new problems that were unaffordable in the past. As a result, numerical simulation and modeling have become a useful tool that complements experimental techniques and helps science and innovation to increase the performance and reliability of new products and services. The study of complex materials such as liquid crystals, polymers, metamaterials, and complex phenomena (e.g., nonlinearities, anisotropy, among others) have been dramatically improved due to these new methods. Their accuracy and the potential to predict and interpret experimental and analytical results have permitted addressing new applications and increasing knowledge in complex phenomena. This Special Issue is focused on recent contributions in the development of numerical methods and modeling applied to Materials Science in the field of optics. It is my pleasure to invite you to submit your work in the form of original research articles or reviews. Potential areas and applications include but are not limited to the following:

Areas:

  • Finite-difference models;
  • Analytical and approximated solutions for optical media;
  • High-performance and optimization solutions for demanding problems;

Applications:

  • Liquid crystals;
  • Polymers;
  • Nanomaterials;
  • Holography;
  • Nonlinear materials;
  • Biosensors;
  • Diffractive optical elements.

This work presents recent results derived from the rigorous modelling of holographic polymer-dispersed liquid crystal (H-PDLC) gratings. More precisely, the diffractive properties of transmission gratings are the focus of this research. This work extends previous analysis performed by the authors but includes new features and approaches. More precisely, full 3D numerical modelling was carried out in all analyses. Each H-PDLC sample was generated randomly by a set of ellipsoid geometry-based LC droplets. The liquid crystal (LC) director inside each droplet was computed by the minimisation of the Frank elastic free energy as a function of the applied electric field. The analysis carried out considered the effects of Frank elastic constants K11, K22 and K33; the anchoring strength W0; and even the saddle-splay constant K24. The external electric field induced an orientation of the LC director, modifying the optical anisotropy of the optical media. This effect was analysed using the 3D split-field finite-difference time-domain (SF-FDTD) method. In order to reduce the computational costs due to a full 3D tensorial analysis, a highly optimised method for high-performance computing solutions (HPC) was developed. The influences of the anchoring and voltage on the diffraction efficiencies were investigated, showing the potential of this approach. Full article

Title: Accurate, efficient and rigorous numerical analysis of 3D H-PDLC gratings

Abstract:
This work presents the recent results derived from the rigorous modelisation of holographic polymer-dispersed liquid crystal (H-PDLC) gratings. More precisely, the diffractive properties of transmission gratings are the focus of this research. This work extends previous analysis performed by the authors but including new features and approaches. More precisely, a full 3D numerical modelisation is carried out in all analysis. Each H-PDLC sample is generated randomly by a set of ellipsoid geometry-based LC droplets. The liquid crystal (LC) director inside each droplet is computed by the minimisation of the Frank elastic free energy as a function of the applied electric field. The analysis carried out considers the effects of Frank elastic constants K11, K22, K33, the anchoring strength W0, and even the saddle-splay constant K24. The external electric field induces an orientation of the LC director, modifying the optical anisotropy of the optical media. This effect is analysed using the 3D split-field finite-difference time-domain (SF-FDTD) method. In order to reduce the computational costs due to a full 3D tensorial analysis, a highly optimised method for high-performance computing solutions (HPC) has been developed. The influence of the anchoring and voltage on the diffraction efficiencies is investigated showing the potential of this approach.
