Abstract

This experimental paper studied the effect of a single and double optical microbottle resonator's effect on ethanol gas sensors. The MBR is formed in two different sizes by the ``soften-and-compress'' technique from silica fiber SMF28. The characterization procedure for both single and double MBR can have Q-factor >10(5) with insertion loss value between -18 dBm until -20 dBm. The MBR then experienced ethanol gas sensing with sensitivity, linearity, stability and repeatability performance defined by transmitted power value and wavelength shift results. Ethanol gas is used from 10% to 100% ppm on every procedure. Single MBR-B, which is slightly bigger than single MBR-A, manage to have excellent performance after all. The size of MBR influenced the sensor to be better in a sense. However, double MBR shows more exquisite performance than single MBR, where numbers of MBR affect the sensor performance after all.
