Application Of The Tlm Technique To Integrated Optic Component Modelling

The TLM algorithm is of high interest to simulate new integrated optical devices as a 'photonic band gap (PBG) structures. These components are realized with semiconductor material and constituted by a set of abrupt optical discontinuities. The electromagnetic behaviour of these structures does not allow the use of usual simulation methods of integrated optics. Indeed, their validity conditions are not satisfied. Then, we have to use unusual simulation method for integrated optics as TLM software which allows the visualization and understanding of the behaviour of electromagnetic field in the PBG structures. In this paper, the simulation results of different optical devices made from the TLM method are presented. Copyright (C) 2001 John Wiley & Sons, Ltd.
