Light coupling from optical fiber to glass?

[QUOTE="Mary09, post: 6831568, member: 731565"] Unfortunately i cannot use completely solid glass as i need the capillary to melt in the metal wire. However i can melt quite a large part at the end of the capillary without major deformation but there is still a very small channel. The only option would be to open the capillary at some point and use a vakuum pump (this is the way we melt in the metal wires). The resulting glass ball at the end works also as a ball lens and i could reduce the losses a bit. I will try with the pin to make a cone shape, how would you recommend to place the fiber then? butt-coupling directly into the cone? I am not sure if i got your idea with the coaxial waveguide, additional shielding of the capillary (e.g. acrylate or another metal)? An LED 365 nm is connected to the fiber. [/QUOTE]
