Effect of PMMA and PVA coating on the performance of optical microbottle resonator humidity sensors

This article compares the performances of uncoated and coated optical microbottle resonators (MBR) for humidity sensing. A technique called ``soften-and-compress'' was used to form the MBR with midriff diameter of D-b = 190 mu m, stem diameter of D-s = 125 mu m and bottle length of L-b = 1...
