Abstract

Applying the advances in electronic and optical computer aided design (CAD) to optoelectronic systems requires precision simulation of electrooptic (EO) devices. In this paper we present a simple but accurate method of modeling EO devices using, as an example, lanthanum-modified lead titanate zirconate (PLZT) with compositions 9.X/65/35. These ferroelectric ceramics have strong EO effects and are cost effective and are therefore excellent candidates for use in optoelectronic systems. In the absence of field the ceramic is optically isotropic whereas an applied field induces anisotropy and optical birefringence. This electrooptic response has been modeled as a classic Kerr quadratic effect [1] as well as a combination of linear and quadratic effects [2]. However, these techniques fall short of accurately modeling fabricated devices, which will be required for optoelectronic CAD tools.
