Title: Innovations of Yu Liu in Optical Waveguide Technology.
Introduction
Yu Liu is a prominent inventor based in Birmingham, GB. He has made significant contributions to the field of optical waveguide technology, holding a total of 2 patents. His work focuses on methods and devices that enhance the functionality of optical waveguides.
Latest Patents
Yu Liu's latest patents include innovative methods for fabricating a regenerated optical waveguide grating. This process involves hydrogenating an optical waveguide and exposing a grating section to a UV laser beam interference fringe pattern to form a Type I grating. The grating section is then exposed for a second period to erase the Type I grating, followed by a third period that allows a regenerated optical waveguide grating to form. Notably, the resonant wavelength increases during this third period, transitioning from being substantially the same as the final wavelength of the Type I grating. Another significant patent is for a dual-parameter optical waveguide grating sensing device and sensor. This invention includes a first optical waveguide grating of a first resonant wavelength in one section of the optical waveguide and a second optical waveguide grating of a second resonant wavelength in another section. The first and second gratings are designed to have different coefficients of rate of change of wavelength as a function of temperature while maintaining substantially the same coefficient of rate of change of wavelength as a function of strain.
