Abstract :
Optical characterization of LiNbO3 whispering gallery mode micro-resonators fabricated by surface tension reshaping is reported. A U-shaped silica fibre taper with a waist diameter of about 2μm was used to couple light in and out of the microresonator. It was observed that when approaching the resonator the fibre taper is attracted by the surface of the structure and loads the cavity. A tunable laser source was used to observe the resonances of the WGM structure. In order to investigate the resonances the light transmitted through the fibre taper and the light scattered from the resonator were monitored during the wavelength scanning process.
