通过具有适当峰值相位偏差的任意奇数相位调制的相位调制单边带零差检测，将光信号的幅度和相位线性转换为低频幅度和相位。当引入额外的幅度调制或通过采用双相位调制或单边带检测器时，对于大范围的峰值相位偏差，可以实现分别小于1%和1°的绝对幅度和相位误差。使用集成马赫-曾德干涉仪对 LiNbO 3 进行的测试测量与理论结果非常吻合。
The amplitude and phase of optical signals are linearly transferred into a low frequency amplitude and phase by phase modulated single sideband homodyne detection with an arbitrary, odd phase modulation of appropriate peak phase deviation. When introducing an additional amplitude modulation or by employing double phase modulation or a single sideband detector, absolute amplitude and phase errors less than 1 percent and 1°, respectively, are achieved for a large range of the peak phase deviation. Test measurements with integrated Mach-Zehnder interferometers on LiNbO 3 are in excellent agreement with the theoretical results.
