PURPOSE:To easily and quickly align the optical axis of a semiconductor PN junction element to that of an optical waveguide without damaging by moving the semiconductor PN junction element by probe opening/closing mechanisms to align the optical axis. CONSTITUTION:Movement of a PN junction element 1 is controlled through a heat sink 23 by probe opening/closing mechanisms 42 and 42' consisting of conductive materials and is controlled by a probe opening/closing mechanism 43 which is orthogonal to mechanisms 42 and 42' and consists of a conductive material. Optical axes of the element 1 and optical waveguide 16 and 16' are aligned if laser beam from optical waveguides 16 and 16' of an optical module are made incident and the element 1 is positioned so that the indicated value of a selecting level meter 15 between probes 41 and 40 connected to mechanisms 43 and 42 is maximum, and in this state, the optical module which fixes the heat sink 23 and a waveguide 18 is generated. By this optional axis alignment free from thermal and mechanical stress, the optical axis of the semiconductor PN junction element is easily and quickly aligned to that of the optical waveguide without damage.
