| 總結: | The research paper defined the effect of polyvinyl alcohol (PVA) coating on optical microbottle resonator (MBR) for sodium alginate concentration sensor. The resonator made from silica fiber SMF28 used a technique known as “soften-and compress”. The MBRs size is based on the three parameters, which is bottle diameter (Db), stem diameter (Ds) and bottle length (Lb). The MBR was then coated with PVA and named MBR-PVA-A, MBR-PVA-B and MBR-PVA-C. The coated MBR-PVA was then coupled with microfiber for characterisation and able to have Q-factor >105
for all conditions. The MBR-PVAs were then used for the sodium alginate sensor with liquid concentrations ranging from 1% to 6%. The MBR-PVAs performance is ultimately excellent, where the results are based on transmitted power and wavelength shift analysis. The MBR-PVAs are promising as sodium alginate concentration sensors by the sensitivity, linearity, stability, and repeatability performance. |
