The resonator includes an active layer, a current confinement layer, a first semiconductor layer having a first doping concentration formed at a side opposite to the active layer across the current confinement layer, and a second semiconductor layer having a second doping concentration higher than the first doping concentration formed between the first semiconductor layer and the current confinement layer. The first electrode is provided to contact a part of a surface of the first semiconductor layer. The first semiconductor layer has a diffusion portion into which a component of the first electrode diffuses. The second semiconductor layer contacts the diffusion portion. The second semiconductor layer is positioned at a node of a standing wave at a time of laser oscillation of the semiconductor laser element. | 2011-10-27 |
20110261853 | NITRIDE SEMICONDUCTOR DEVICE AND METHOD FOR FABRICATING THE SAME - A nitride semiconductor device includes a first nitride semiconductor layer formed on a substrate, a defect induced layer formed on the first nitride semiconductor layer, and a second nitride semiconductor layer formed on the defect induced layer, contacting the defect induced layer, and having an opening through which the defect induced layer is exposed. The defect induced layer has a higher crystal defect density than those of the first and second nitride semiconductor layers. | 2011-10-27 |
