摘　　要：硅基长波红外集成光电子器件是集成光学发展的一个新兴领域.阐述了利用等比例放大原理设计该波段下的slot波导的思路,分析了波导的限制因子、偏振特性等性质,并提出了工作波长为10.6μm的偏振无关slot波导定向耦合器.The research of long-wave infrared silicon waveguided components is triggered by the development of integrated optic devices. The validity of Scale-up principle for designing the size of slot waveguides in this waveband is demonstrated; the characteristics such as contain factor and polarization were explained. The polarization-independent optical directional coupler based on slot waveguides was attained at the wavelength of 10.6μm.
