Lead-Lanthanum Zirconate-Titanate (PLZT) Electrooptic Variable Focal-Length Lens with Stripe Electrodes

Abstract

This paper proposes new types of one and two-dimensional electrooptic (E-O) lenses of simple structure. The two-dimensional lens is composed of two one-dimensional E-O lenses which are arranged to converge light beams perpendicular to each other. The refractive index distribution of the lens is calculated using the finite-element method, and ray tracing is performed by solving the ray equation for each one-dimensional lens. Parameters of the E-O lens, such as electrode width and gap, and crystal thickness, are optimized. One and two-dimensional lenses are demonstrated, and the focusing and temporal characteristics are studied experimentally.
