What does it imply when we say that the waves are perfectly correlated?
I am having a hard time understanding difference between correlation and coherence. I got a nice answer for coherence here- Are two waves being in phase is the same as saying that the two waves are ...

The importance of optical period in coherent radiation
I am reading a text on coherent radiation and not quite understanding a particular statement. To provide some background, the authors state that coherent radiation can arise from light-matter ...

How is the temporal coherence of a pulse defined?
I am having problem with the concept of coherence and photon degeneracy.
The temporal coherence of pulse is defined in Born and Wolf as:
$$t_c=\lambda^2/c\Delta\lambda$$
(The time a photon takes to ...

Coherence, Correlation and causality in Quantum Field Theory
I've started to study in details quantum optics and I find difficulties in linking the concepts of coherence and correlation among fields, especially because I'm building right now a background on ...

First-order coherence of thermal light
so I have the following question: I want to calculate the first order coherence function for the light coming from a thermal source. I should note that this is a question I have and not a HW problem.

Wiener-Khinchin theorem for multimode coherent light
The Wiener-Khinchin theorem says that the Fourier transform of the degree of first order coherence is equal to the power spectral density normalized (Loudon, Quantum theory of light, pag. 102):
$F(\...

Modelling incoherent sources
Suppose some (coherent) light propagates onto a one-dimensional barrier with two open slits, each of length $\delta$ and separated by a distance $s$ (we can assume the centroid is known and placed at $...
