Abstract :
Selective excitation of an extended range of whispering gallery modes (WGM) supported by bottle microresonators fabricated on a short section of optical fiber is demonstrated experimentally and discussed theoretically. Decrease of the observed Q factors, as the excitation point moves away from the bottle centre, are associated with increased mode leakage. Compared to standard-fiber cylindrical resonators, the bottle microresonator results in a 35times increase of the observed Q factor.
