摘要 | Distributed feedback-laser diodes are provided. The distributed feedback-laser diode may include a substrate, a lower cladding layer having a grating on the substrate, an active layer disposed on the lower cladding layer, a first upper cladding layer disposed on the active layer, a phase-shift region extending in a first direction on the first upper cladding layer, and a ridge waveguide layer extending in a second direction crossing the first direction on the phase-shift region. |
其他摘要 | 提供分布式反馈激光二极管。分布式反馈激光二极管可包括基板,在基板上具有光栅的下包层,设置在下包层上的有源层,设置在有源层上的第一上包层,以及在其中延伸的相移区域。第一上覆层上的第一方向和在相移区上与第一方向交叉的第二方向延伸的脊形波导层。 |
主权项 | A distributed feedback-laser diode comprising: a substrate; a lower cladding layer having a grating on the substrate; an active layer disposed on the lower cladding layer; a first upper cladding layer disposed on the active layer; a phase-shift region extending in a first direction on a side of the first upper cladding layer opposing the active layer; and a ridge waveguide layer extending in a second direction crossing the first direction on the phase-shift region. |
