Figure 4.

Calculated ray-tracing during the evaporation of fluid from within a MC. An initial phase of low propagation losses (a) is followed by an intermediate phase of large loss (b–d), as reflected rays do not reach the core of the output fiber. Transmitted power recovers gradually towards the end of the evaporation process (e–f). The values of O(t) for panels (a–f) were 9.5 μm, −1 μm, −8.5 μm, −35 μm, −110 μm, and O(t) →∞, respectively.
