A process for the coupling of an electrically driven cavity-enhanced quantum dot light source to a single-mode fiber is presented. Due to interference effects, the coupling efficiency depends sensitively on the distance between the light source and the fiber tip. The measured coupling efficiency is in excellent agreement with numerical simulations using JCMsuite.
