Abstract :
Recently the nonlinear spectrum deformation and the position shift of resonances in microspheres have been investigated. In order to explain both effects (broadening and shifting), numerical calculations based on the mean field approximation for the field inside the microsphere and relaxation equations for the temperature have been performed. The spectrum response exhibited a typical behaviour for bistable resonators. Good quantitative agreement between experimental data and numerical calculations has been obtained.
