Photothermal heating represents a major constraint that limits the performance of many nanoscale optoelectronic and optomechanical devices including nanolasers1, quantum optomechanical resonators2, 3, and integrated photonic circuits4. Although radiation-pressure damping has been reported to cool an individual vibrational mode of an optomechanical resonator to its quantum ground state2, 3, to date the internal material temperature within an optomechanical resonator has not been reported to cool…
