    (a) Fabrication steps of the sensing probe; (b) microscopic images of the sensor probes with different thickness film.
    Schematic diagram of the experimental setup.
    Microscopic images of the cross-section view of (a) uncoated fiber facet, (b) facet only coated with UV adhesive, and (c) facet with aluminum film coated on UV adhesive; (d) SEM image of the probe after aluminum film coating.
    FL energy of probe I before and after coating with aluminum under the different excitation laser powers.
    Ray tracing simulations are shown in (a)–(d). The simulations are conducted using Optgeo.
