| 中文摘要: |
| III V族微腔激光器中的P型金属电极通常采用的Ti Pt Au的合金方式，而其中的Ti层对通信波长1 550 nm的激光具有很强的吸收，不适合在高密度光子集成器件中使用。为了代替传统的合金方式，采用二维解析法计算单一金属Al和Ag金属限制下的微腔中光学模式品质因子，发现这两种新型电极具有更小损耗。另外在实验上分别制作金属Al和Ag的电极的微腔激光器，得到与理论预测一致的测试结果。由于这两种电极价格便宜，工艺简单并与CMOS工艺相容，因此在光子集成器件中具有很高的应用前景。 |
| 英文摘要: |
| P type metallic electrode in III V microcavity lasers traditionally adopt the Ti Pt Au alloys mode, while the Ti layer has a strong optical absorption for the laser at the communication wavelength 1 550 nm, which is not suitable for the application in photonic integration. In order to replace the traditional alloy method, this paper calculates the optical model quality factor in the microcavity under the constraints of single metal Al and Ag metal using analytical method, and found that these two new electrodes have smaller optical losses. In addition, experiments were carried out on the micro cavity lasers with electrodes of metal Al and Ag, respectively, and the results were well consistent with the theoretical predictions. Moreover, the two electrodes are cheap, simple and compatible with CMOS process, so they have high application prospects in photonic integration. |
