Study on Angle Deviation for Coupling Loss in Fiber Collimator Packaging

Angle deviation of optical components in fiber collimator packaging is theoretically analyzed, and 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). Then the economical tolerance of collimator assembly, which provides the theoretical foundation to establish MOEMS mathematic model of packing collimator and realize industrialized production, is confirmed.
