Figure Lengend Snippet: (a) Transmittance test results for HCF and MMF samples when the light source with a power of 7.7 mW was coupled to the 3-cm long fibers. The measured transmission power was 3.51 ± 0.024 mW for HCF and 1.90 ± 0.072 mW for MMF. (b) The forbidden zone and allowed zone of the commercial HCF sample. When the hollow core is filled with air, the resonance frequencies range from 1490 to 1680 nm. (c) When the hollow core is filled with glucose solution, this leads to a shift of the resonance wavelengths, causing a redistribution of the allowed transmission band. The allowed zone has a range from 820 to 924 nm and this band covers the wavelengths of Raman signal.
