Question WLS fiber surface 

Forum: Geometry
Date: 17 Jun, 2011
From: Yusuf Erdogan <Yusuf Erdogan>


Im just trying to design a WLS-fiber (double-cladded) and have a question about the surface. There should be two ways to consider the two cladding-layers coating the fibercore.

1. I place the fibercore in the volume of cladding-layer1 and then both of them in the volume of cladding-layer2 to prevent any overlap or unwanted thin gaps between the volumes. But since there is apparently a problem with these placements if the solid is a torus (the fiber is curved), i dont consider this case. (Also this way i cant define a border surface between the fibercore and cladding-layers?!)

2. I careful place both fibercore and cladding-layers in the world: First the fibercore, then the cladding-layer1 coating the core, at last cladding-layer2 coating both fibercore and cladding-layer1. In this case i have to define several optical surfaces for all transitions (core-clad1, clad1-clad2, clad2-world)...

The second option seems to work, but it is on the one hand not really elegant, on the other hand very susceptible towards any slips :).

Further i have learned, that there is also a opportunity to use G4LogicalSkinSurface to implement thin cladding-layers to the surface of fibercore. But i have no idea how to do this (i know the examples from the talks of Peter Gumplinger)
