Abstract

The angle deviation in the packaging of fiber collimator is theoretically analyzed, and the resolution expression of the relationship between angle deviation of components and coupling loss of collimator is deduced due to transmission equation of GRIN (Gradient Index Lens).And it is pointed out that, angle deviation of optical components will cause off-axis coupling between two fiber collimators in a single fiber collimator assembly. For collimator coupling between collimators is more sensitive to angel matching, secondly to off-axis. So, in the assembly of the collimator, the angle deviation of optical components is one of the most important reasons causing coupling efficiency loss. If coupling efficiency loss of collimator is given, by this equation we could get the range of angle deviation, and then get assembly tolerance. Optimal tolerance of fiber collimator assembly put forward in the paper provides theoretic foundation to establish MOEMS of fiber collimator reasonable packaging technology and technique demands. It is practically beneficial for improving industrial production efficiency, the product characteristics and quality, and realizing the optic-machine-electrical integration assembly of fiber collimator.
