Popis: In this work we investigate the behavior of anisotropic multilayer structures. A coupled thermo-optic multilayer model is used to simulate the static and the dynamical intensity and polarization response of interference filter with an anisotropic central layer of LiNbO3. Bringing the electro-optic and the thermo-optic properties together leads to new possibilities for controlling the bistable behavior of such a structure. It has been shown numerically that the longitudinal dependence of the temperature distribution can not be neglected for multilayer structure in general. We show that the thermo-optic response of an anisotropic resonator gives rise to both intensity and polarization bistable loops. The quantitative comparison of the simulations with the experimental data confirms the necessity of considering the 3D temperature distribution inside the filter. Our numerical predictions are compared with the experimental results, showing a very good agreement. The obtained results open new perspectives for further investigation and optimization of anisotropic interference filters, focusing on the interesting phenomenon of polarization driven optical bistability. Besides, the model can be used in the thermal engineering for many other active multilayer devices, where the thermal effects can not be neglected.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
