| 摘 要： | 通过分析AWG中心波导倾角特性,优化焦点间距,提出了两个结构约束方程,得出了结构紧凑的AWG设计方法.根据这一方法,可以由一定损耗条件下的最小弯曲半径和接口参数—接口处输入/输出波导间距和最短直波导长度,优化并完全确定其它结构参数,从而得到最小面积的AWG波导结构.最后给出了优化设计实例. |

| Abstract: | It is very important that the larger number of chan nels of AWG can be obtained on a definite wafer. The compact design of AWG presented in this paper was based on two restricting equations and optimizing the distant between the two focuses of AWG through analyzing the inclination of central waveguide. A design method was proposed, by which the rest structure parameters can be exactly determined with the minimum bending radius of waveguides, pitch of adjacent input/output waveguides, and a desired compact AWG can be obtained. An example was presented at last. |
