全光模数转换器namsx并行量化编码方法

Complete optical A/D converter, NAMSX paralleling quantification coding method

Abstract

本发明公开一种全光模数转换器NAMSX并行量化编码方法,设计N位模数转换器:稳定的探测光脉冲和控制光脉冲(模拟光)经波分复用器或偏振耦合器[1]输入1×N耦合器[2]分束再输入N个非对称迈克耳孙干涉仪[3];每个非对称迈克耳孙干涉仪[3]反射口前设置光纤环行器[4],透射输出口处设置通带滤波器或检偏器[5]仅允许探测光通过。以上结构结合适当的耦合器[2]分束比及每个非对称迈克耳孙干涉仪[3]的耦合器分束比使探测光并行输出光格雷反码。
The invention discloses a full-optical analog-digital converter NAMSX parallel quantizing coding method, which designs a N-bit analog-digital converter: a stable detection optical pulse and a control optical pulse (an analog light) input 1XN couplers [2] light splitting via a wavelength division multiplexer or a polarization coupler [1] and then input N asymmetrical Michelson interferometers [3]; each asymmetrical Michelson interferometer [3] is provided with a fibre circulator [4] at a reflection hole thereof; a pass filter or an analyzer (5) is provided at a transmission output hole to only permit the detection light to get through. The above structure with proper coupler [2] light splitting ratio and the coupler light splitting ratio of each asymmetrical Michelson interferometer enables the detection light to output light Grey complement code.
