Abstract:
1. A two-wavelength semiconductor laser device, comprising: a first conductive material substrate having an upper surface with first and second regions separated from each other thereon; a first semiconductor laser diode comprising a first conductive material first clad layer, a first active layer and a second conductive material first clad layer sequentially laminated on the first region of the first conductive material substrate; a non-active layer formed on the second region of the first conductive material substrate and comprising the same layers as those of the first conductive material first clad layer, the first active layer and the first conductive material second clad layer of the first semiconductor laser diode; a second semiconductor laser diode comprising a first conductive material second clad layer, a second active layer and a second conductive material second clad layer sequentially laminated on the non-active layer; and a lateral conductive region formed at least between the first and second semiconductor laser diodes such that the first conductive material second clad layer and the first conductive material substrate can be electrically connected to each other.
