Abstract :
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
