摘要:
A semiconductor optical device includes a first clad layer, a second clad layer and an optical waveguide layer sandwiched between the first clad layer and the second clad layer, wherein the optical waveguide layer includes a first semiconductor layer, a second semiconductor layer disposed on the first semiconductor layer and extending in one direction, and a third semiconductor layer covering a top surface of the second semiconductor layer, and wherein the first semiconductor layer includes an n-type region disposed on one side of the second semiconductor layer, a p-type region disposed on the other side of the second semiconductor layer, and an i-type region disposed between the n-type region and the p-type region, and wherein the second semiconductor layer has a band gap narrower than band gaps of the first semiconductor layer and the third semiconductor layer.
