AI Thread Summary
Mix polarization refers to the dynamics of polarization states in semiconductor waveguides, particularly under anisotropic Kerr non-linearity. The discussion highlights that stationary solutions and their stability can be analyzed using Stokes polarization parameters, leading to insights into mixed-polarization spatial soliton dynamics. These dynamics can be understood as mixtures of pure polarization states, where time-dependent changes can occur between linear and circular polarizations. The equations governing the electric and magnetic fields can be decoupled into two separate equations, illustrating the concept of mixed polarization. Overall, the exploration of these dynamics provides a deeper understanding of polarization behavior in optical systems.

i faced this term in a special paper. i can't figure it out what it exactly means.

Can you provide more context?

sure:
"Polarization dynamics are considered in the presence of an anisotropic Kerr non-lin-
earity in the most common semiconductor waveguide geometry. The equations of
motion are formulated in terms of Stokes polarization parameters and their Hamiltonian
form is derived. Stationary solutions and their stability are found for plane-wave prop-
agation. It is found that the non-integrable problem of mixed-polarization spatial soliton
dynamics can be largely explained in terms of the equivalent plane-wave solutions."

sorry to be so slow to respond.

It sounds like the solutions- either solitons or plane waves- are mixtures of pure polarization states. If the polarization state changes in time (i.e. linear to circular and back again), the state can be written as a time-dependent mixture of two orthogonal polarization states.

Can you provide a proper attribution to the article?
 
can i understand it like this:

vector E and B are restricted by a series of equations.
if we write it into components, the equations decouples into two decoupled equations. otherwise, we can say it is mixed polarization
 
Thread 'A quartet of epi-illumination methods'
Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...
I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
