| 英文摘要 | An optical semiconductor device is provided with a core layer (20) having a quantum well layer in which a film thickness gets thinner and the width gets wider from an inner region to an end portion in an optical waveguide region. Such a device can provide an improved efficiency of optical coupling between the active optical element and an optical fibre. The waveguide is made of a multi quantum well grown by selective area growth using a patterned mask geometry. |
