<p><P>PROBLEM TO BE SOLVED: To provide an optical communication module which can be simply assembled by solving such a problem in the conventional optical communication module that the adjustment of optical axis is difficult and the assembly accuracy can not be enhanced. <P>SOLUTION: In the optical communication module, at least a first optical member, a second optical member and a third optical member are arranged in this order on an optical path of optical communication and, therein, the positional alignment is performed on the basis of the first optical member. The third optical member is not coupled to the second optical member but is positioned by directly being coupled to the first optical member as reference. The positioning and optical axis alignment can be simply performed, the positional deviation is not integrated and the deviation of optical axis as the total module can be reduced. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
