Numerical simulation of thin-film electro-optic beam deflectors

In this paper, we present numerical simulations, based on the beam propagation method (BPM), of a Gaussian beam deflected by a thin-film electro-optic (EO) deflector. The results are compared to geometric optics calculations and experimental data. From the BPM simulation, it is clear that one should choose a larger number of interfaces for prism-like EO deflectors in order to obtain a predictable deflection angle and good beam quality.<>
