Integrated PLZT-based optical phased array structures for three-dimensional optical memory addressing

摘要

Materials for three dimensional optical memories have been the focus of significant research. The development of appropriate optical addressing technologies have been cited as critical to the practical exploitation of the potential density and throughput achievable in three dimensional optical memory architectures. Coherent optical arrays have been cited as an undeveloped but potentially groundbreaking component in the optical addressing of three dimensional memories. Designs and simulations for PLZT based single and multiple lobe optical phased arrays are presented. These PLZT based optical phased array structures implement optical scanners and scanning optical array generators. The physical structure of the devices can be varied to allow operation at a specific optical wavelength and optical beam resolution. The integrated optical scanners and scanning optical array generators can be implemented with simple three-port voltage dividers and dc current drivers. These devices could provide the geometric reconfiguration of optical pathways required of addressing schemes in three dimensional optical memory architectures.
