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.
