Title: You Chia Chang: Innovator in Optical Technology
Introduction
You Chia Chang is a prominent inventor based in Taichung, Taiwan. He has made significant contributions to the field of optical technology, holding two patents that showcase his innovative approach to solving complex problems in photonics.
Latest Patents
One of his latest patents is an optical head capable of providing sub-wavelength beams. This invention includes a transparent substrate, a thin film, and a surface structure with a sub-wavelength surface profile. The incident light transmits through the transparent substrate, forming a surface plasma wave along the sub-wavelength aperture located within the thin film. The light is then re-emitted through spatial coupling with the sub-wavelength profile of the surface structure. This technology can maintain a waist smaller than the diffraction limit for a few micrometers out of the surface, making it applicable in micro or nano manufacturing, metrology, and manipulation using light beams.
