We have experimentally demonstrated the existence of optical whispering-gallery-modes (WGMs) with quality factors in excess of 108 in elliptical cavities fabricated with LiNbO3. The efficiency of evanescent coupling to the modes through a diamond prism was as high as 97.3%. This is the best value ever achieved for evanescent coupling to a WGM resonator using a prism. The free spectral ranges of the WGMs are successfully modeled using an eikonal approximation.
