【Abstract】 The principle of making the silicon V-grooves and the feasibility of manufacturing high accuracy linear optical fiber array with the silicon V-grooves were introduced,and the main factors influencing on the accuracy of the devices were analyzed and they will be extremely considered in the process of designing and making the devices.By requirement of the devices,the characteristics of the adhesive used for adhesion of the optic fibers were analyzed and the ultraviolet epoxy adhesive was experimentally compared with the infrared adhesive.The results indicate that the Norland ultraviolet epoxy adhesive and the 353ND infrared adhesive are the optimum adhesives.The silicon V-groove array was prepared by anisotropic etching process,and then the fibers were arranged and adhered in corresponding V-grooves.After treatment of orientation and end section,a high accuracy linear optical fiber array was prepared.After the error of the end section and the surface roughness were measured,the results indicate that the error of end sections of the fibers is less than and equal to 3 240 nm and the root-mean-square value of the surface roughness is less than or equal to 3.85 nm.更多还原
