We study an optomechanical cavity, in which a buckled suspended beam serves as a mirror. The mechanical resonance frequency of the beam obtains a minimum value near the buckling temperature. Contrary to the common case, in which self-excited oscillations of the suspended mirror are optically induced by injecting blue detuned laser light, in our case, self-excited oscillations are observed with red detuned light. These observations are attributed to a retarded thermal (i.e., bolometric) force…
