By using prism coupling to a square µ cavity, over 75% energy transfer to the whispering gallery modes (Q>10[sup 6]) by frustrated total internal reflection was observed. A good comparison was found between measured data and theoretical model (based on a Fabry-Perot resonator), for the dependence of the coupling and linewidth of the whispering gallery modes (WGMs) as a function of relative separation between the prism and the µ cavity. By selecting the incident angle at the prism interface, the coupling to all four different sets of WGMs can be changed to coupling to only one set of WGMs.
