Latest Patents

Wu's latest patents include a "Holographic Grating Lithography System and a Method for Adjusting the Self-Collimation of the Interference Optical Path Thereof." This innovative system utilizes a Volume Bragg grating (VBG) positioned behind a collimating lens. The incident angle of the exposure light beam is set to match the Bragg angle of the VBG. A photodetector is strategically placed in the -1 grade transmission diffraction light path of the VBG, allowing for real-time observation of the photodetector's readings. The method for adjusting the self-collimation optical path replaces traditional Moire pattern adjustment techniques, enhancing precision in optical applications.

Another significant patent is the "Method for Manufacturing Holographic Blazed Grating." This method involves several steps, including coating a photoresist layer on a substrate, performing lithography to create a photoresist grating, and utilizing vertical ion beam etching to transfer the pattern onto the substrate. The process culminates in the creation of a triangular groove shape of the blazed grating, resulting in a high-quality holographic blazed grating.
