When light transmitting through two interfaces of wave-guide, the luminous energy of coupling losses great for the condition of Snell Law, which restricts the wide application of coupling more optical elements. It has obstructed the development of the integrated optics.
但是由于光线在透过两波导界面传输时，受到Snell定律的制约，光能耦合损耗很大，导致三个元件以上的集成光路不能走向应用，阻碍了大规模集成光路的发展。
