Title: Yaying Weng and a Barium Strontium Titanate Photorefractive Device
Introduction
Yaying Weng is an inventor associated with Fuzhou, China, and the Chinese Academy of Sciences. His patent work includes a photorefractive device made from barium strontium titanate (BST) single crystal.
Latest Patents
Weng’s listed patent, “Barium strontium titanate photorefractive device and method for making,” describes a device based on a single crystal with a composition substantially represented by Ba₁₋ₓSrₓTiO₃, where 0.01 < x < 0.1. The manufacturing method involves growing the crystal using the Czochralski technique, annealing it in an oxidizing atmosphere, machining it into a cuboid with polished surfaces, and mechanically and electrically poling it into a single-domain state.
The device can consist of a piece of the single-domain crystal or an optoelectronic assembly that uses the crystal as its core component. Its reported performance is similar to that of a device made from barium titanate, and a reflectivity of up to 52% was achieved when it was used as a self-pumped phase conjugator. The patent reports that BST crystal production can offer a shorter typical growth period of three to four days, simpler equipment and process requirements, higher yield, and greater ease in obtaining larger crystal cuboids. Weng is listed with 1 patent.
Career Highlights
Weng’s documented patent contribution focuses on the growth, processing, and application of BST single crystals for photorefractive devices. The invention connects materials engineering with optoelectronic applications and describes a manufacturing approach intended to improve crystal production.
