| 英文摘要 | The present invention is to provide an optical integrated device formed on the GaAs substrate and with reduced dispersion of the optical coupling of the but-joint between the active and the passive devices. The GaAs substrate of the invention is divided into two regions, and the lower cladding layer extends over both regions. The active layer, having a quantum well structure with band-gap energy smaller than 3 eV, is arranged of the lower cladding layer in the first region, while the GaAs core layer is also arranged on the lower cladding layer but in the second region thereof. Thus, the cure layer may optically couple with the active layer. |
