| Abstract: | Optical waveguide polarizer at 632.8 nm,in X-cut,Y-transmission,was fabricated using proton exchange conjunction with Ti diffusion in LiNbO3. The variation mechanism of refractive index was analyzed in Ti diffusion waveguides and proton exchange waveguides,and the various factors affecting the device performance were analyzed as well. The experiment results are in great agreement with theoretical calculation, which achieve the requirements of the integrated optical circuits, and provide theory basis for the research of other polarizers. |
| Keywords: | Ti diffusion proton exchange extinction ratio insertion loss |
