摘要
报道了一种利用光电负反馈技术产生开环非经典强度相关光场的串联耦合ＬＥＤ系统。实验观察到孪生光束强度差的量子涨落低于标准量子极限（ＳＱＬ）约８９％的噪声压缩。研究表明，本方案装置简单，成本低下，压缩量大，有着广阔的应用前景。
A new serial coupled LED system generating open loop nonclassical intensity correlation light field by using a technique of negative feedback is described in the paper.We have observed that the the quantum fluctuation of the intensity difference between open loop twin beams is less than about 89% of the noise compression of the standard quantum limit in the experiments.The investigation shows that the concept has the advantages such as simple structure,low cost and large compression quantity.It can be applied to many fields.
