Title: Innovations by Fengqing Wu in Optical Fiber Technology
Introduction
Fengqing Wu is a notable inventor based in Duluth, GA, who has made significant contributions to the field of optical fiber technology. With a total of 7 patents to his name, Wu's work focuses on enhancing the efficiency and performance of optical fibers through innovative methods.
Latest Patents
Wu's latest patents include groundbreaking techniques for increasing the cladding-to-core ratio (D/d) of low D/d core rods in optical fiber preforms. One of his patents describes a method where core rod sections are fabricated by inserting core body pieces axially end-to-end inside a glass cylinder. This process involves heating the cylinder and core body pieces in a furnace, allowing them to elongate and collapse into a finished core rod. The core rod sections can then be cut from this rod for use in optical fiber preforms. Another patent outlines a similar method where multiple core body pieces are inserted into a glass cylinder, which is then heated to form a core rod with a D/d ratio greater than five. This innovative approach allows for the production of optical fiber preforms with a D/d ratio of about 15 or more, enabling direct drawing of optical fibers from the preform.
