摘要 | An array (48, 49, 50, 51 ) of fiber optic couplers coupling an input (45) and an output (46) waveguide. The output waveguide (46) is routed among the couplers of the array such that either backward or forward coupling exists. With backward coupling, energy coupled into the output waveguide (46) in a coupler of the array is guided back to the preceding coupler for coupling back into the input waveguide (45). The backward coupling allows recirculations to occur between couplers to create poles and zeroes in the transfer function of the array which transfer function can be programmed or tailored somewhat to have specific characteristics. Further, the backward coupling allows the array to be used for matrix-vector multiplication. |
其他摘要 | 光纤耦合器的阵列(48,49,50,51)耦合输入(45)和输出(46)波导。输出波导(46)在阵列的耦合器之间布线,使得存在后向或前向耦合。利用反向耦合,耦合到阵列的耦合器中的输出波导(46)中的能量被引导回到前面的耦合器,以耦合回到输入波导(45)中。向后耦合允许在耦合器之间发生再循环,以在阵列的传递函数中产生极点和零点,其中传递函数可以被编程或稍微定制以具有特定特征。此外,后向耦合允许阵列用于矩阵向量乘法。 |
