1. A method of fabricating a semiconductor laser capable of switching a polarization mode of output light, said method comprising the steps of:

  • fabricating a first semiconductor laser structure, a gain for a first polarization mode being larger than a gain for a second polarization mode in the first semiconductor laser structure; and

    fabricating a second semiconductor laser structure independently from said fabricating step of the first semiconductor laser structure, a gain for the second polarization mode being larger than a gain for the first polarization mode in the second semiconductor laser structure; and

    arranging the first semiconductor laser structure and the second semiconductor laser structure along a waveguide direction on a common support member such that the first and second semiconductor laser structures-are optically coupled to each other.
