| 摘 要： | 用有限元-人工透射法计算权重耦合的可调谐声光滤波器(AOTF).计算过程中,考虑了2种权重函数:余弦函数和高斯函数;同时给出了AOTF滤波响应特性的数值计算结果.通过比较,可以得出具有高斯权重耦合函数的AOTF的TE-TM模转换滤波响应比具有余弦权重函数的AOTF的TE-TM模转换滤波响应更好.结果与其他文献能很好得吻合,说明该方法能有效地模拟计算AOTF. |

| Abstract: | Finite element-artificial transmitting method is applied for acoustooptic tunable filters(AOTF) with weighted coupling.Here,two kinds of weighting function are considered:one is Cosine function,the other is Gaussian function;and then the numerical results are shown for AOTF with different weighing function.Through comparison,the optical filter responses of the TE-TM mode conversions of AOTF with Gaussian weighting function are better than AOTF with Cosine weighting function.The results are in good agreement with others,which illustrates that this method is useful in calculation on AOTF. |
| Keywords: | finite element artificial transmitting boundary acousto-optic tunable filters weighted coupling mode conversion |
