我们提出了一种新的矩阵方法来证明在平面光波导的转折点的相移是完全等于π，而不是π/2或其他值。我们还表明存在的相位贡献，从反射的子波，据我们所知，从来没有考虑到以前。
We present a novel matrix approach to proving that the phase shift at a turning point in a planar optical wave-guide is exactly equal to pi rather than to pi/2 or to some other value. We also show the existence of phase contributions from reflected subwaves, which to our knowledge have never been taken into account previously.
