This paper presents 2D Finite Difference Time Domain (FDTD) and Finite Element (FE) modeling of Liquid Crystal (LC) devices. The enhancements to standard FDTD required for fully non-diagonal tensor materials such as LCs are outlined and they have been implemented in an in-house code. The results have been validated against a commercial FE package and good agreement is observed. The codes are then used to study in-filling of Photonic Crystal devices, in particular a benchmark structure being used a part of the COST P11 activity is used. Results are shown for transmission through the device and the effects of LC in-filling and director field rotation are seen. © 2006 IEEE.
