提出并论证了一种全光模数转换器的新方法。一个单相调制器和一个连续波半导体激光器被用来调制正弦音调模拟信号。软件采样测量产生的有效位数为4.1。拟议设置的优点是其设计简单、带宽高和稳定性。该方案主要在光域中受相位调制器的速度限制，在电子域中受电比较器和逻辑器件限制
A novel approach of an all-optical analog-to-digital converter is proposed and demonstrated. One single-phase modulator and a continuous-wave laser diode are used to quantize the sinusoidal tone analog signal. Software sampling measurements yielded an effective number of bits of 4.1. Benefits of the proposed setup are its simple design, high bandwidth, and stability. The scheme is primarily limited in the optical domain by the speed of the phase modulator and in electronic domain by electrical comparators and logic devices
