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 D-b, stem diameter of D-S and bottle length of L-b. The Q-factor defined by coupled with tapered microfiber with 2 mu m 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.
