Motionless Dynamic System for 3-D Optical Memory Based on PLZT Electro-Optic Lenses

Abstract

The objective of this effort is to design, fabricate, and test a device that uses the electro-optic effort for laser beam focusing and beam steering. The technology is applicable to standard and next generation optical disk subsystems and 3-D volumetric optical memories. The report presents experimental results of a two-dimensional electro-optic dynamic diverging lens. The device is based on a lanthanum-modified lead zirconate titanate (PLZT) ceramic wafer. The continual change of focal length is achieved by an applied control voltage. The design of the device takes a simple form and is almost free of diffraction loss.
