| 摘要 |
A method to assemble a pig-tailed optical module and an arrangement thereof are disclosed. The method includes a step to recover the optical coupling efficiency between the optical device in the optical module and the pig-tailed fiber. The method includes a step to iterating the YAG laser welding at points axially distributed but with an inconstant pitch as slightly rotating the optical module around the optical axis of the pig-tailed fiber clock wise and counter clock wise depending on the enhancement and/or the degradation of the optical coupling efficiency between the optical device and the pig-tailed fiber. |
