提出并论证了一种利用光互连实现光子模数转换的光编码方案。它允许我们将多功率电平信号转换成多位二进制码，以便通过二进制光电二极管阵列以位并行的格式进行检测。所提出的光学编码是在使用自频移进行光学量化之后执行的。基于二进制转换表的光学互连通过适当分配作为光学量化的结果提供的电平识别信号来生成多位二进制码。实验结果表明，8级模拟脉冲可转换为3位并行二进制码。
We propose and demonstrate an optical coding scheme using optical interconnection for a photonic analog-to-digital conversion. It allows us to convert a multi-power level signal into a multiple-bit binary code so as to detect it in a bit-parallel format by binary photodiode array. The proposed optical coding is executed after optical quantization using self-frequency shift. Optical interconnection based on a binary conversion table generates a multiple-bit binary code by appropriate allocation of a level identification signal which is provided as a result of optical quantization. Experimental results show that 8-levels analog pulses are converted into 3-bit parallel binary codes.
