Quantum interference approach to two-photon correlation phenomena of chaotic light
No full textWe present a quantum two-photon interference approach to two-photon correlation phenomena of chaotic light, including the historical experiment of Hanbury Brown and Twiss. We argue against the interpretation of such phenomena in terms of a classical statistical correlation between intensity fluctuations. To support our view, we show a 'ghost' imaging experiment with chaotic light for which the classical understanding does not give a satisfactory interpretation. We also provide a two-photon optical picture of ghost imaging with chaotic light in terms of two-photon phase-conjugate mirrors which is very advantageous because it yields lensless two-photon imaging, suggesting imaging applications for radiations for which no effective lens is available
Two-photon correlation of chaotic light: A quantum interference phenomenon
No full textTwo-photon correlation phenomena of chaotic light, including the historical Hanbury Brown and Twiss effect, are essentially the quantum effect of two-photon interference, instead of the classical statistical correlation between intensity fluctuations. To support our view, we analyze a "ghost" imaging experiment with chaotic light for which the classical understanding does not give a satisfactory interpretation. We also provide a two-photon optical picture of ghost imaging with chaotic light in terms of a two-photon phase-conjugate mirror, which suggests lensless imaging applications for radiations for which no effective lens is available
Can Two-Photon Correlation of Chaotic Light Be Considered as Correlation of Intensity Fluctuations?
No full textTwo-photon correlation phenomena, including the historical experiment of Hanbury Brown and Twiss, may have to be described quantum mechanically, regardless of whether the source of radiation is classical or quantum. Supporting this point, we present a ghost imaging type of second-order spatial correlation experiment of chaotic light to show that the classical understanding based on the concept of statistical intensity fluctuations does not give a correct interpretation for the observation. From a practical point of view, this experiment demonstrates the possibility of having high contrast lensless two-photon imaging with chaotic light, suggesting imaging applications for radiations for which no effective lens is available
Quantum magic mirror and imaging
No full textWe experimentally show that chaotic light can behave as a "magic" mirror producing real images using second order correlation measurements. A ghost imaging scheme using the "magic" mirror is demonstrated and possible applications are discussed
