PURPOSE:To make dislocation of optical axis hard to be caused. CONSTITUTION:A waveguide route type optical device is constituted of a waveguide route substrate 1, upper splines 2, a support glass 3, a semiconductor laser 5 mounted on a pipe 6 having a flange and a lens 4 to converge outgoing light from the semiconductor laser 5, and the waveguide route substrate 1, the upper splines 2 and the support glass 3 are stuck together, and end face polishing is carried out so as to be on the same plane. On the one hand, the semiconductor laser 5 and the lens 4 are housed after their positions are adjusted beforehand so that the outgoing light from the semiconductor laser 5 can be converged in a flange part of the pipe 6 having the flange through the lens 4. End faces of this waveguide route substrate 1 and the flange surfaces of the pipes 6 having the flange are brought into close contact with each other, and are fixed together after the optical axis is adjusted. |
