Efficient excitation and phase matching of fiber-coupled degenerate whispering gallery modes

The ability of optical whispering gallery mode (WGM) resonators to store energy in a very small volume for a long time enables their use in practical applications as low-threshold lasers, high-sensitivity sensors, and tunable add-drop filters. In this paper, we express in detail the tapered fiber ...
