Title: Innovations of Dongning Wang
Introduction
Dongning Wang is a prominent inventor based in Hong Kong, China. He has made significant contributions to the field of optical technology, holding a total of seven patents. His work focuses on advanced methods and devices that enhance the capabilities of fiber optics.
Latest Patents
One of his latest patents is titled "Fiber Bragg Grating in Micro/Nanofiber and Method of Producing the Same." This innovative method involves fabricating Fiber Bragg gratings in a micro/nanofiber using ultrashort pulse irradiation. The process includes elongating and flame-brushing a single mode optical fiber to create a micro/nanofiber, followed by generating ultrashort pulse irradiation to induce refractive index changes at predetermined intervals within the micro/nanofiber. The ultrashort pulse propagates through a focusing element and a diffractive element before reaching the micro/nanofiber.
Another notable patent is the "Fiber In-line Mach-Zehnder Interferometer (MZI) Device." This device is designed for temperature sensing or refractive index sensing. It comprises a section of Photonic Crystal Fiber (PCF) with air holes infiltrated with a liquid analyte, forming a waveguide channel. The liquid analyte creates rods in the PCF, which leave an interference fringe pattern in the transmission spectrum when light is injected into the PCF. The fringe dips are tracked over a wide wavelength range to sense temperature or refractive index.
