(a) Transmitted power of the microsphere-based setup, calculated for three resonant ${\mathrm{WGM}}_{l,m,n}$, as a function of the modal order X of the ${\mathrm{LP}}_{0,X}$ cladding modes, with a gap g = 0 nm; (b) transmission of the ${\mathrm{WGM}}_{774,774,3}$, excited by the ${\mathrm{LP}}_{0,5}$, as a function of the detuning $\Delta \omega$, with a gap g = 0 nm; microsphere-based setup.
