Abstract
Silica microresonators with an inverted-wedge shape were fabricated using conventional semiconductor fabrication methods. The measured quality factors of the resonators were greater than in 1550 nm band. Controllable coupling from under coupling, through critical coupling, to over coupling was demonstrated by horizontally moving a fiber taper while in touch with the top surface of the resonator. Thin outer ring of the resonator provided a support for the fiber taper leading to a robust stable coupling.
