How can the electric field of optical fibers be visualized?

AI Thread Summary
The discussion focuses on visualizing the electric field of optical fibers, comparing it to dielectric slab waveguides where field expressions can be used to illustrate the electric field and its characteristics. Participants express interest in obtaining similar visual representations for optical fibers, noting the presence of zeros in the core and exponential decay in the cladding. However, there is a lack of readily available images or resources that depict these field expressions for optical fibers. A suggestion is made to conduct a Google search for relevant images, but specific examples are not found. The conversation highlights the need for better visual resources related to the electric fields in optical fibers.

Hello!
For dielectric slab waveguides, starting from the field expressions, it is possible to draw the Electric field corresponding to a specific mode, showing its (possible) zeros inside the core and its exponential decay in the cladding:

A Google search can provide plenty of images like this one.
What about optical fibers instead? Is it possible to obtain an equivalent image, which corresponds to the obtained field expressions?
I couldn't find them.

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...

Thread 'Effective absorption coefficient of gold nanoparticles'

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...
