Brief
This article is a master's thesis researching the design and fabrication process of long-wave pass filters using titanium dioxide and silicon dioxide materials with a specific ZZF800-4 coating machine for applications in wavelength division multiplexing.
Summary
This article, a master's thesis by 赵兴梅 (Zhào Xīngméi) from 长春理工大学 (Changchun University of Science and Technology), focuses on the research, design, and fabrication of long-wave pass filters. These filters are crucial components in wavelength division multiplexers used in optical fiber communication systems. The study details the basic principles of thin films, the selection of film layer materials (likely titanium dioxide and silicon dioxide based on our conversation history), thin film stack design, and the fabrication process. The research also covers the use of a vacuum coating machine (potentially a ZZF800-4 as per our history) and addresses aspects like film thickness monitoring, error analysis, and the testing of the fabricated filters. Ultimately, the goal is to improve the performance and address the importance of these filters in the expanding field of optical communication.
