我们报告了阵列波导光栅（AWG）复用器-解复用器中相位和幅度误差导致的色散。我们测量了两种不同类型 AWG 的相位和幅度误差分布，并讨论了它们对色散的影响。结果表明，AWG中色散的根源是对称相位和反对称幅度误差的低阶傅立叶分量。我们还讨论了在存在相同制造误差的情况下色散对通带形状的依赖性。
We report dispersion resulting from phase and amplitude errors in arrayed-waveguide grating (AWG) multiplexers-demultiplexers. We measure the phase- and amplitude-error distributions of two different types of AWG and discuss their effects on the dispersion. The results show that the origin of the dispersion in the AWG is the low-order Fourier components of the symmetric phase and the antisymmetric amplitude errors. We also discuss the dependence of the dispersion on the passband shape in the presence of the same fabrication errors.
