摘要
基于高重复频率低抖动激光器,结合波分复用和时分复用,设计了一套高采样率高精度的光采样系统。给出了光采样量化精度、采样率与采样脉冲时间抖动以及幅度抖动的关系。分析了系统的偏振特性及减小色散累积时间抖动、光纤折射率引起的时间抖动的措施,同时讨论了高功率短脉冲激光在光纤中传输的非线性效应抑制措施。
In this paper, an all Optical Analog-to-Digital Converter （OADC） system is designed and demonstrated, which con- sists of a high-repetition-frequency laser with low-time-jitter, a Wavelength Division Multiplexer （WDM） and an Optical Time Division Multiplexer （OTDM）. Then, the relationship between the quantification accuracy and sampling rate, and the sam- piing pulse jitter and the amplitude jitter is given. Finally, the polarization characteristics of this system are analyzed and the measures for minimizing the timing jitter caused by accumulated dispersion and by fiber refractive rate and for suppressing the nonlinear effects of high-power short pulse laser in transmission in fibers discussed.
