We demonstrate controlled lifting of the azimuthal degeneracy of the whispering gallery modes (WGMs)
of single glycerol­water microdroplets standing on a superhydrophobic surface by using a uniform elec-
tric field. A good agreement is observed between the measured spectral positions of the nondegenerate
