Abstract:
1. A method of manufacturing a two-wavelength semiconductor laser device, comprising the steps of: a) preparing a first conductive material substrate; b) laminating a first conductive material first clad layer, a first active layer and a second conductive material first clad layer on the first conductive material substrate in sequence; c) laminating a first conductive material second clad layer, a second active layer and a second conductive material second clad layer on the first conductive material substrate in sequence; d) removing an intermediate region of a semiconductor structure laminated in the step c) such that the semiconductor structure can be divided into a first region and a second region, followed by removing the first conductive material second clad layer, the second active layer and the second conductive material second clad layer from a portion corresponding to the first region; and e) forming a lateral conductive region formed at least between the first and second regions such that the second conductive material first clad layer of the second region and the first conductive material substrate are electrically connected to each other.
