I poured a droplet that has 1.55 refractive index (RF) over a fiber that has core and cladding with (RI) 1.45 and 1.4 respectively, and I the molecules aggregated over the fiber, known that because the refractive index of the liquid is higher than of than of the core or the cladding a leakage of light from fiber to the droplet happens. The number of propagated modes in the fiber is three modes and the diameter is 13 micrometer.
So I have two questions:
1- So why they aggregate over the fiber? What do you think the scenario is?!
2- Does the shape or the polarization of the three modes still the same in the droplet as in the fiber? Because the shape (or the cross section) of the fiber with respect to the surface is arch...
The image on the left depict the experiment and the image on the right shows the cross section of the fiber.
