Title: Hsien-Tzu Chang: Innovator in Fiber Bragg Grating Technology
Introduction
Hsien-Tzu Chang is a noted inventor based in Judung Jen, Taiwan. With a remarkable two patents to his name, Chang has made significant contributions to the field of photonics, specifically in the fabrication of Fiber Bragg Grating elements.
Latest Patents
Hsien-Tzu Chang's latest patents include a pioneering method for fabricating Fiber Bragg Grating elements and related planar light circuits. This innovative method involves the use of a mask with a predetermined pattern and a wafer, where a light-guiding channel filled with a light-guiding substance is established. The process begins with forming a photoresist layer over the wafer. Chang then manipulates the magnification of a photolithography apparatus to adjust the first magnification, transferring the mask pattern to the photoresist layer to create an initial pattern. Subsequently, the light-guiding substance not covered by the photoresist layer is cleared away, enabling the first pattern to be imprinted onto the light-guiding channel, ultimately resulting in the formation of a Fiber Bragg Grating element. This methodology is crucial for advancements in optical technologies.
