Single Photon Interference and the Hong-Ou-Mandel (HOM) Effect in an Interferometer
Reading on the Hong-Ou-Mandel (HOM) effect, I came to wonder how exactly we can be certain that interference that occurs in apparatuses such as a Michelson interferometer and Mach-Zehnder ...

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 $...

Slit size vs. object size in double slit experiment
In classical optics, the double slit experiment show interference of light. The spacing of the fringes at a distance $z$ from the slits is given by
$$
w \approx \dfrac{z \lambda}{d} \;,
$$
where $d$ ...

Why would energy conservation be violated during interference if a wave function represented multiple photons?
the below paragraph is from Paul Dirac's 'The principles of quantum mechanics'. He argues that representing multiple photons' probability distribution via a single wavefunction leads to energy ...

Beam splitter that splits two incoming beams differently
ב"ה
Is there any way to build a beam splitter that will split two incoming beams differently?
Say, beam coming from the left (x axes) will transfer 70% and reflect 30% while beam coming from ...

What's the physical origin of bound states in the continuum (BICs)?
From my point of view, BICs are modes built by destructive interference. But I'm confused about the orgin of BIC, I have two questions:
The differences between BIC modes and defect modes.
It has ...

Why is there a single slit in the Young double-slit experiment? [duplicate]
I am studying waves these days and my teacher just introduced Young double-slit experiment, which has always been brilliant (see picture below).
However, I have a question: why is there a single slit ...

Interference of two phase-modulated photons
Results about the quantum mechanical formulation of single-photon Mach-Zehnder set-up are already accessible.
However, it is not obvious how two photons interfere when we have applied an arbitrary ...

Photon Interference in a double slit experiment [duplicate]
I have been trying to understand interference of photons.
I used to think of a photon like a localized wave, with an electric and magnetic field travelling perpendicular to each other, each possessing ...

Linear Polarization of Single Photon?
I've heard it said (a while ago) that we don't usually speak of a single photon being linearly polarized or unpolarized, but rather we can speak of an ensemble of photons that are linearly polarized ...

Why won't my interference pattern go away?
Bought a double slit diaphragm, laser pointer and some linear polarizing sheets off of Amazon so I could see the double slit experiment first hand.
When I place a vertically aligned polarizer in ...

electron double slit experiment manipulating interference pattern
Let us suppose we can change the magnetic field and the charge on the interference surface like shown in the picture.
Would it be possible to move our interference pattern along the y-axis by changing ...

Evolution of the operators in Mach-Zehnder interferometer
I have trouble understanding how the operators that change the initial state, change when adding extra splitters. As an example, I will use an idealized Mach-Zehnder interferometer where the splitters ...
