- 摘要：
- We report on the two-photon superbunching effect of thermal light via constructive multiple two-photon path
interference, showing the possibility of controlling the bunching property of thermal light in a linear optical
system. By inserting n pairs of mutually first-order incoherent optical channels as a cascade into the traditional
Hanbury Brown and Twiss (HBT) interferometer, the two-photon bunching peak-to-background ratio of thermal
light can be increased by up to 2 × 1.5n, surpassing the theoretical upper limit of 2 for a traditional HBT
interferometer. Experimentally, the ratio was measured to be 2.4 ± 0.1 when one pair of optical channels was
inserted. Such a scheme can be viewed as a prototype of a two-photon grating.
