AI 中文摘要
我们提出通过一种改进的法布里-珀罗腔来增强经典光的聚束效应,该腔的一个腔镜被空间光调制器所取代,通过该调制器,多个独立的横向调制(每个调制独立地在光波前上编码空间相关的相位)在腔内的纵向传播方向上依次级联。测量得到所产生的超聚束光场的双光子聚束峰和三光子聚束峰分别为 $36.9\pm2.0$ 和 $\rm (2.46\pm0.12)\times10^{3}$,与热光相比,分别提高了一个数量级和三个数量级。相应地,实验证明,用超聚束光重建的鬼成像可见度比用赝热光重建的提高了约40倍。这种经典超聚束光场不仅对基础物理具有重要意义,而且在相关成像、鬼干涉和非线性光学等潜在应用中也很重要。
英文摘要
We proposed to boost the photon bunching effect of classical light via a modified Fabry-Pérot cavity with one of the cavity mirrors being replaced by a spatial light modulator, through which multiple independent transverse modulations, each was to encode independently spatially correlated phase on the wave front of the light field, was cascaded in sequence in the longitudinal propagation direction in the cavity. The two-photon bunching peak and the three-photon bunching peak of the generated superbunching light field were measured to be $36.9\pm2.0$ and $\rm (2.46\pm0.12)\times10^{3}$, respectively, which, as compared to those of thermal light, were improved by one-order and three-order of magnitude, respectively. Correspondingly, the ghost image visibility reconstructed with the superbunching light was demonstrated experimentally to be improved by $\sim 40$ times as compared to that with the pseudo-thermal light. Such classical superbunching light field is of essential importance not only for fundamental physics but also for potential applications such as correlated imaging, ghost interference and nonlinear optics.
