How in Faraday rotator, changing magnetic field will change the refractive index of RCP and LCP?
Can anyone mathematically prove how in the faraday rotator, when we change the magnetic field direction, it will change the refractive index of Right circularly polarized (RCP) and Left circularly ...

Refractive indices of liquid crystal
Refractive indices of liquid crystal • The birefringence is critical to the optical properties of the liquid crystal and underlies many of the applications of liquid crystals. • By reorienting the ...

Physical origin of Kerr effect
I was wondering if someone could explain to me the physical (not mathematical) origin behind the Kerr effect and why it results in birefringence in materials.
Also, can the birefringence be introduced ...

Birefringence in uniaxial materials
In linear optics, when treating anisotropic uniaxial materials we get the frensel equation
this equation gives us two solution for n. My problem is that according to Snell's law, if I have two ...

Why is Nicol prism cut at 68 degrees specifically?
Why not just some other angle but this specific one? Does it help in some way to polarize the ray?
I have tried searching everywhere, but they only show that the crystal is cut at an angle of 68 ...

Birefringent materials and Maxwell equation
Maxwell's equations define the speed of light in a given medium at a given point through the equation:
$$\frac{\partial^2E}{\partial t^2}=\mu\epsilon\nabla^2E$$
so according to it, the speed of light ...

Circular polarizer filter wavelength dependency?
I don't fully understand the circular polarizer filter (CPL) for my camera. It contains a linear polarizer and a quarter wavelength plate (QWP). The QWP causes a time delay between the ordinary and ...

Birefringent filters: Showing that phase shift is inversely proportional to wavelength from my data
I started out by taking two sets of data for the crossed and parallel setup without the birefringent filter. The crossed setup being when destructive interference occurs and the parallel being ...

Vacuum Birefringence with alternating EM waves
I read [1] that in the presence of strong static electric or magnetic fields in vacuum the refractive index changes in such a way that there is a difference of refractive index between parallel and ...

Why do we need cross-polarised light for observing conoscopic interference patterns?
I've performed some experiments for projecting conoscopic interference patterns. In some set-ups are used two circular polarizers one before and one after the birefringent crystal. I can imagine that ...

Vacuum birefringence
Many of the papers (e.g., this) dealing with nonlinear electrodynamics treat a theory's prediction of vacuum birefringence as undesirable, but don't explain why it would be undesirable. For example:

Does the polarized light lose intensity when it crosses a birefractive crystal?
If a beam of light coming from a natural source passes through a polarizer and then through a birefringent crystal, does the intensity with which it left the polarizer change?
