The process that light wave gets through arrayed waveguides can be regarded as a process of extracting spatial sample and filtering spatial frequency . spacial sample is accomplished by period interval arrangement of awg and spatial frequency filtering is accomplished by the fundamental mode and phase delay of each arrayed waveguide which is just a spatial frequency filter 而光场通过阵列波导的过程,可八硕士学住论文waiaster ’ stiesis以看作是空间抽样以及空间滤波的过程:空间抽样由阵列波导的周期间隔排列完成,空间滤波由每个阵列波导的基模形式以及位相延迟完成(阵列波导即为一空间滤波器) 。
