From the single - slit diffraction experiment of apparatus for fraunhofer diffraction, it is seen that, in the single - slit diffraction pattern, while incident light is perpendicular to single - slit plane, bright fringe appears in the middle and symmetrical arrays of bright fringe with gradually decreasing intensity appear on both sides
從夫朗和費衍射裝置的單縫衍射實驗中可以看到：在入射光垂直於單縫平面時的單縫衍射實驗圖樣中，中間有特別明亮的亮紋，兩側對稱地排列著一些強度逐漸減弱的亮紋。 -
The angle spectrum of inputting optical signals is received by the input surface of arrayed waveguides. whereas the diffraction process of light beam outputed in slab waveguide is a process of " composing frequency and generating image ". the reason that fraunhofer diffractive pattern can be gained on outputting waveguide surface is that output ends of arrayed waveguide distribute on the arch structure which leads bent phase factor to offset the quadratic phase factor in fresnel diffraction
輸入平板波導內光束的衍射過程是「分頻成譜」的過程，在陣列波導的輸入面接收到的是輸入光信息的角譜；而輸出平板波導內光束的衍射過程則是「合頻成像」的過程，正是由於陣列波導輸出口排列分佈在圓弧形結構上，其彎曲位相因子消去了菲涅耳衍射中的二次位相因子，從而在輸出波導面上能夠得到夫瑯和費衍射圖樣。
