| 英文摘要 | PURPOSE:To adjust a minute coupling deviation, and also, to facilitate the automatizing of an optical axis adjustment by quadri-secting one end of a pipe in advance and bending them orthogonally, and fixing them to the incident light part of an isolator. CONSTITUTION:One end of a lens guide 4 is quadri-sected in advance, and fixed to the end face of an optical isolator 27 by resistance welding 5 or YAG welding. In this state, when the cylindrical side face of the lens guide 4 is pushed in the (x) direction, the vicinity of a welding zone of the lens guide 4 is brought to plastic deformation, the adjusting alignment in a longitudinal direction can be executed, and similarly, the alignment in the lateral direction is executed in the (y) direction. At the time of adjusting an actual lens pipe in the (x) direction, first of all, a position in which the maximum optical output is obtained is derived by deforming the lens guide 4, and after loading a little larger load than this deformation load, the load is removed. In this state, the optical output is checked, and compared with the maximum output, and in the case the output does not reach the maximum, the load is further added, and this operation is repeated. In such a manner, even in the case the isolator optical axis and the incident light do not coincide with each other, the optical axis can be allowed to coincide by bringing the lens guide 4 to fine adjustment deformation. |
