摘　　要：为了减小波分复用器的器件长度,在聚酰亚胺材料的基础上,设计了一种赝态结构的2×2多模干涉波分复用器,并分别用精确导模分析法对其进行模拟分析和优化设计。结果表明,赝态结构波分复用器可以有效地对980nm和1550nm光进行解复,并且器件尺寸只有传统设计的1/5。器件在器件长度和波长变动中显示出良好的容差性,并且能够和掺铒放大器与激光器实现集成。其中,赝态结构MMI聚酰亚胺波分复用器的干涉区宽度和长度以及输入口宽度和距离对其性能均有影响。To shorten the wavelength-division-multiplexer, a quasi-state is applied to a 2×2 multi-mode interference multiplexer/demultiplexer on fluorinated polyimide. The device is analyzed and optimized by explicated modal propagation analysis. The results show that the device can demultiplex for the 980 nm and 1 550 nm with the 1/5 length of normal designed device. Moreover, the device has high tolerance on the device length and wavelength variation and can be integrated with erbium doped amplifiers and lasers. The capability of device can be affected by the width and length of the interference or the width and distance of the input.
