Lumerical Files Provisional Patent on Modelling Optical Response of Liquid Crystal Devices

(Nanowerk News) Lumerical Solutions, Inc., a global provider of optoelectronic design software, announced the filing of a provisional patent application titled, "System and Method for Transforming a Coordinate System to Simulate an Anisotropic Medium." The patent application, filed with the US Patent and Trademark Office, describes how the optical response of dispersive, spatially varying anisotropic media can be efficiently simulated on a discretized grid like that employed by finite-difference time-domain (FDTD) or finite-element method (FEM) simulators. The invention disclosed is relevant to a wide array of applications including liquid crystal display (LCD) panels, microdisplays, spatial light modulators, integrated components using liquid crystal on silicon (LCOS) technology like LCOS optical switches, and magneto-optical elements in optical communication and sensing systems.
According to Dr. James Pond, the inventor and Lumerical's Chief Technology Officer, "many next generation opto-electronic products combine complicated materials and nano-scale structure, which is beyond the capabilities of existing simulation tools. Lumerical's enhanced framework allows designers to accurately simulate everything from liquid crystal displays to OLEDs, and silicon photonics to integrated quantum computing components."
Lumerical's new methodology for efficiently simulating anisotropic media is part of a larger effort to allow designers the ability to model the optical response of many different types of materials. In addition to the disclosed invention, Lumerical has added a material plugin capability which will enable external parties to include complicated material models, such as those required for modelling semiconductor lasers or non-linear optical devices, into FDTD-based simulation projects.
These latest achievements complement their proprietary Multi-Coefficient Materials, providing designers with the ability to accurately and efficiently model dispersive, spatially varying anisotropic media. Together with their subcell-accuracy Conformal Mesh Technology, Lumerical's FDTD Solutions and MODE Solutions products offer a flexible design environment for the simulation of sophisticated opto-electronic technologies. According to Chris Koo, an engineer with Samsung, "Lumerical's latest innovation has established them as the clear leader in the field of optoelectronic device modeling. Their comprehensive material modeling capabilities paves the way for the development of exciting new technologies."
