| titleOfInvention | Integrated optical isolator and manufacturing method thereof |
| abstract | To provide a reliable semiconductor optical isolator that operates in correspondence with a TE mode in which many semiconductor lasers operate and appropriately protects a semiconductor optical amplifier active layer. In this case, a structure is provided in which a new waveguide layer is provided so that a relatively large amount of light is concentrated on the waveguide layer. A ferromagnetic layer is formed on the side wall of the waveguide layer. A ferromagnetic layer is disposed on the side wall of the waveguide layer, and a part of light leaks laterally from the waveguide layer to reach the ferromagnetic layer, thereby obtaining optical isolation. That is, since there is no need to process the active layer, it is not exposed and the reliability is not deteriorated. [Selection] Figure 1 |
