abstract = "Dissipation of the energy stored in the modes of a cylindrical microcavity with minor radius variations perturbs the temperature of the resonator, significantly affecting the mode structure. We experimentally demonstrate that thermal drifts not only shift the mode spectrum as a whole but also alter the free spectral range between adjacent axial modes and give rise to new eigenmodes. Through a numerical model, we show that in microresonators suitable for low-frequency comb generation, the thermally induced dispersion can be comparable to the mode linewidth. Fortunately, the positive sign of the dispersion does not hinder the modulation instability required for nonlinear generation.",

N2 - Dissipation of the energy stored in the modes of a cylindrical microcavity with minor radius variations perturbs the temperature of the resonator, significantly affecting the mode structure. We experimentally demonstrate that thermal drifts not only shift the mode spectrum as a whole but also alter the free spectral range between adjacent axial modes and give rise to new eigenmodes. Through a numerical model, we show that in microresonators suitable for low-frequency comb generation, the thermally induced dispersion can be comparable to the mode linewidth.
