Fig. 10From: Integrated end-to-end instrumentation for the study of whispering gallery modes in dynamic liquid micro-cavities coupled to sub-micron tapered fibersWaist diameter of a fiber as a function of pulling time/pulling length. Red points are the experimental data points and the blue curve is an exponential fit to Eq. 3. Pulling speed v was 20 μm/s and by fitting the data, the hot-zone length h was found to be 2.0 mmBack to article page
