论文摘要
这对于用真正的混沌光观察高级奔放效果是一项挑战，我们在这里提出并展示了一种实现二阶一致性程度的高级奔放效应的方法，其基于层叠的米其尔森干预仪（CMI）的宽带固定混沌光为2.42，超过了两种效果的理论上限。超阳性相关峰是用超快速两光吸收检测器测量的，该检测器的全宽度在一半最大范围内约为95 fs。开发了CMI中的两光子超级挑战理论以解释效果，并与实验结果一致。该理论还预测，如果混乱的光在CMI中传播$ n $ times，二阶连贯性的程度可能大于$ 2 $。最后，提出了一种新型的弱信号检测设置，该设置采用了在CMI中循环的宽带混沌光。从理论上讲，在CMI中混沌光循环100次后，它可以增加弱信号的检测灵敏度。
It is challenging for observing superbunching effect with true chaotic light, here we propose and demonstrate a method to achieve superbunching effect of the degree of second-order coherence is 2.42 with broadband stationary chaotic light based on a cascaded Michelson interferometer (CMI), exceeding the theoretical upper limit of 2 for the two-photon bunching effect of chaotic light. The superbunching correlation peak is measured with an ultrafast two-photon absorption detector which the full width at half maximum reaches about 95 fs. Two-photon superbunching theory in a CMI is developed to interpret the effect and is in agreement with experimental results. The theory also predicts that the degree of second-order coherence can be much greater than $2$ if chaotic light propagates $N$ times in a CMI. Finally, a new type of weak signals detection setup which employs broadband chaotic light circulating in a CMI is proposed. Theoretically, it can increase the detection sensitivity of weak signals 79 times after the chaotic light circulating 100 times in the CMI.
