基于弄弯的聚合物更复合的一个波长部门平面波导被建议。根据联合模式理论和波导结构,弄弯的波导 coupler (CWC ) 的表演被分析。结果证明 CWC 能由于有效联合长度的赔偿效果比平行直波导 coupler (SWC ) 提供更宽的 multiplexing 带宽。二个变量,弯曲半径和最小的间距,增加波导设备的设计灵活性。A 4 隧道波长部门 multiplexing (WDM ) 系统基于 CWC 被设计。由于半径和最小的间距在制造期间处理的弯曲的错误,中心波长的偏差被调查。弯曲半径和最小的间距越小,中央波长偏差由弯曲半径和最小的间距的错误引起了越多 larger 是,它为设计和聚合物波导设备的制造提供某有用理论基础。这个工作部分是的 CLC 数字 TN256 由中国(No.60577014 ) 的国家自然科学基础支持了, Dalian 工业大学(号码 893210 ) 的年轻教师耕作基础和 Dalian 工业大学(号码 893322 ) 的医生启动基础。
A wavelength division multiplexer based on curved polymer planar waveguide is proposed. According to the coupled mode theory and the waveguide structure, the performance of the curved waveguide coupler (CWC) is analyzed. The results show that CWC can accommodate wider multiplexing bandwidth than parallel straight waveguide coupler (SWC) due to the compensation effect of the effective coupling length. The two variables, curvature radius and minimum spacing, increase the design flexibility of the waveguide device. A 4-channel wavelength division multiplexing (WDM) system based on CWC is designed. The deviation of the center wavelength, due to the errors of curvature radius and minimum spacing during fabrication process, is investigated. The smaller the curvature radius and the minimum spacing are, the larger the central wavelength deviation caused by the error of the curvature radius and the minimum spacing is, which provides some useful theoretical basis for the design and the fabrication of polymer waveguide devices.
