"fiber ends" is a correct phrase in written English.
You can use it to refer to the two ends of a fiber, for example "The fiber ends were carefully measured before being spliced together."
Two fiber ends are separated by a bulk, nonlinear medium.
In this paper, we connected two single-mode fiber ends with a micron hollow quartz fiber.
By fixing the fiber ends, relaxation of the mesophase above Tg is partially disabled.
This optical fiber sensor first realizes sampling from the surface of the optical fiber rather than the fiber ends.
In the case of fiber lasers, mirrors are often butt-coupled to the fiber ends to avoid diffraction losses.
The fatigue damage initiated at fiber ends in the joint region and then progressed in the monolithic alloy section.
A stress concentration zone is observed around the fiber end.
An optical beam transmitted from one tapered fiber end, propagates through the nonlinear medium and couples back into the other tapered fiber end.
The output fiber end is cleaved in this case with an angle of >10° to eliminate Fresnel reflection.
As degradation time increased, some fiber end surfaces showed signs of further decays.
Based on paraxial approximation, we formulate ABCD transformation matrix of such fiber end.
