Rigorous analysis of whispering gallery mode frequency conversion because of time variation of refractive index in a spherical resonator.
We investigate theoretically the switching effects for the whispering gallery modes in a spherical dielectric resonator when its material is subject to abrupt time change in permittivity. A rigorous analytical approach is used to study the transformation process. Details of both the transient response and the steady-state regime are described.
