论文摘要
电磁I/Q调节器的正确操作取决于调节器内部干涉仪臂之间的相对相位偏见的精确调整和控制。我们提出了一个全分析相位偏置锁定方案，其中从光载体和辅助2 MHz RF-Tone产生的光载体和光学音调之间获得误差信号，以锁定所有三个涉及的干涉仪的相位，以操作高达10 GHz。使用开发的方法，我们在载体抑制的单层带模式下演示了一个I/Q调制器，在该模式下，被抑制的载体和边带锁定在光电水平$ <-27 dB $相对于发射的侧带时。我们描述了一个简单的分析模型，用于计算误差信号，并详细详细介绍用于实现该方法的电子电路的实现。
Proper operation of electro-optic I/Q modulators rely on precise adjustment and control of the relative phase biases between the modulator's internal interferometer arms. We present an all-analog phase bias locking scheme where error signals are obtained from the beat between the optical carrier and optical tones generated by an auxiliary 2 MHz RF-tone to lock the phases of all three involved interferometers for operation up to 10 GHz. With the developed method, we demonstrate an I/Q modulator in carrier-suppressed single-sideband mode, where the suppressed carrier and sideband are locked at optical power levels $< -27 dB$ relative to the transmitted sideband. We describe a simple analytical model for calculating the error signals, and detail the implementation of the electronic circuitry for the implementation of the method.
