Paper Abstract

Liquid crystal filled polymer structures provide switchable optical devices at low cost and with low driving voltages. One such device is a switchable optical grating, current models of these do not fully explain the effects seen within the devices that have been constructed. A new modeling technique has been implemented to better understand these. A comparison of the use of the Oseen-Frank and Landau-De Gennes free energy equations is given. Data from an experimental device is compared to that from simulation and it is shown that the simulation provides both similar results and an aid to understanding the real device.
