Cosmic infrared background — (CIB) is a mysterious infrared light coming from outer space. It is slowly being resolved into specific sources by infrared telescopes. In some ways it is analogous to the cosmic microwave background, but at shorter wavelengths. Contents 1… … Wikipedia
Photon antibunching — generally refers to a light field with photons more equally spaced than a coherent laser field. More specifically, it can refer to sub Poisson photon statistics, that is a photon number distribution for which the variance is less than the mean. A … Wikipedia
