Title: Chang Kuo Chang: Innovator in Waveguide Technology
Introduction
Chang Kuo Chang is a notable inventor based in Singapore, SG. He has made significant contributions to the field of waveguide technology, holding a total of 2 patents. His innovative approaches have advanced the capabilities of high index contrast waveguide structures.
Latest Patents
Chang's latest patents focus on a method to trim and smooth high index contrast waveguide structures. This method involves the formation, through etching, of structures whose minimum width is less than can be achieved by optical means alone. This achievement is realized by inserting a layer of sandwiching material between the photoresist and the structure. By adjusting the relative etch rates of this layer and the structure, a uniform lateral width reduction and surface smoothing of the structure is accomplished.
