提出了一种在绝缘体上硅波导上单向输出的亚波长金属腔InP/InGaAs激光器的新设计。通过设计在波导非输出端形成的集成光反馈短段的长度和形状，我们在保持约束因子的同时提高了整体Q因子。
We propose a novel design of sub-wavelength metallic-cavity InP/InGaAs laser with unidirectional output on a silicon-on-insulator waveguide. By engineering the length and shape of the integrated optical feedback stub, formed on the non-output end of the waveguide, we improve the overall Q factor while maintaining confinement factor.
