Title: Innovations by Weijiong Li in Fiber Splicing Technology

Introduction

Weijiong Li is a notable inventor based in Tucson, Arizona, recognized for his contributions to the field of fiber optics. With a total of three patents to his name, he has developed innovative methods that enhance the performance and reliability of fiber splicing.

Latest Patents

One of his latest patents is a method of fusion splicing thermally dissimilar glass fibers. This technique involves pretreating the cleaved end surface of the high-temperature fiber to create a smooth surface for optimal contact with the low-temperature fiber. The fibers are then heated to a temperature that softens the low-temperature fiber without affecting the high-temperature fiber, allowing for a strong fusion joint. Another significant patent is the method of angle fusion splicing silica fiber with low-temperature non-silica fiber. This low-cost approach results in a low splice loss, low back reflection loss, and a mechanically robust angle-fusion splice. The process includes angle cleaving the silica fiber and square cleaving the non-silica fiber, followed by asymmetrical heating to form the splice. This innovative method enhances the mechanical strength of the joint while reducing splice loss.
