I've been doing some reading about SPDC. I understand the wave mixing, the conservation laws, the coupled equations for the three fields (pump, signal and idle).
But I can't find any good reference on how does the split happens? (how the two photons are created)
Is it because photons of the pump interact with atoms in the crystal and get scattered?
Is some kind of interaction with the grid?
I really don't get this.
The only hint I got is that it must be related with somethin called "two-mode squeezed vacuum".
Can someone please explain this to me? or redirect me to a good reference where I can do my own reading?
Thanks in advance :)
