Parametric oscillation of a moving mirror driven by radiation pressure in a superconducting Fabry-Perot resonator system

A moving pellicle superconducting mirror, which is driven by radiation pressure on its one side and the Coulomb force on its other side, can become a parametric oscillator that can generate microwaves when placed within a high-Q superconducting Fabry-Perot resonator system. A paraxial-wave analysis shows that the fundamental resonator eigenmode needed for parametric oscillation is the TM011 mode. A double Fabry-Perot structure is introduced to resonate the pump and idler modes, but reject the parasitic anti-Stokes mode. The threshold for oscillation is estimated based on the radiation-pressure coupling of the pump to the signal and idler modes and indicates that the experiment is feasible to perform.
