Abstract

We have carried out a systematic study of the effect of microtaper diameter on the spectral characteristics of bottle microresonators. By increasing the microtaper-diameter (Dt) from 2µm to 10µm results in progressively cleaner spectra. The transmission depth at resonance varies from ~15dB (@Dt = 2µm) to >3dB (@Dt = 10µm). The loaded Q factors were measured to be >10+6 in all cases. However, with microtaper Dt = 10µm clearly-resolved single resonance peaks could be observed and free-spectral ranges could be easily identified. At some transmission resonances, we have observed LP01 to LP11 mode transformation at the excitation microtaper waist, for the first time, as the resonance is scanned.
