5. Time reversal symmetry and energy conservation can be used to show that the corresponding four port coupling parameters on the resonator side are identical to the taper side and that κ is purely imaginary.
6. Here the free spectral range corresponds to the intermode spacing in l of the microsphere whispering-gallery modes, where the effective cavity length is the circumference about the equator.
