Fig. 16From: Integrated end-to-end instrumentation for the study of whispering gallery modes in dynamic liquid micro-cavities coupled to sub-micron tapered fibersCavity ring-down signal of a WGM in a silicone oil microdrop. Fitted parameters, V (frequency scanning speed) = 4.6×105 GHz/s, τ (amplitude lifetime) = 54 ns \(\Rightarrow \tau _{photon}\) (photon lifetime) = τ/2 = 27 ns \(\Rightarrow Q = 6.5 \times 10^{7}\)Back to article page
