Abstract

This experimental paper proposes a new method to enhance the ability of microbottle resonator (MBR) sensor through polymethyl methacrylate (PMMA) and polyvinyl alcohol (PVA). The bottle resonator custom used the “soften-and-compress” technique from SMF28 silica fiber, then coated with PMMA and PVA. Three MBR used are non-coated MBR, MBR-PMMA and MBR-PVA. The coated and non-coated MBRs were then characterized via taper microfiber and achieved to have Q-factor >10^5 for all, MBR-PVA is at the top with 8.624x10^5. The MBRs were then experienced as ethanol gas sensors, with the gas percentages used between 1% to 5% ppm. The sensitivity, linearity and stability are measured parameters via transmitted spectral and wavelength shift. The findings show that the MBR-PVA tremendously outraged every observed parameter. Here, the coating may influence the MBR performance as a gas sensor.
