The key point of realizing the optic-machine-electrical assembly of the collimator is to found the reasonable process technology of the fiber collimator packing. In this paper, the coupling loss of assembly deviation of fiber collimator is firstly analyzed, and a theory that pitch deviation between optical components in single fiber collimator packing would cause off-angle coupling between two fiber...
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...
A new scheme for the fabrication of collimate lens for single mode fiber have been developed using liquid droplet of UV cured resin. A small amount of liquid resin is placed on the output surface of single mode fiber to form a collimate lens. The output beam from the fiber through this lens is monitored with a wave-front sensor. The centering error of the fiber position to the ferrule is adjusted...
