Abstract

This paper studied whispering gallery modes on the micro bottle resonator (MBR) as sodium hypochlorite sensor. The MBR designed by method "soften-and-compress" in three different bottle diameters. The parameters named as bottle diameter DS, stem diameter of and bottle length of Lb. The Q-factor defined by coupled with tapered microfiber with diameter and succeeded to have >10^5. The range of sodium hypochlorite concentrations from 1% pmm to 6% pmm was then used for analysis purpose. The performance of the MBRs undeniably excellent with sensitivity linearity and repeatability analysed from wavelength shift and transmitted power.
