Optomechanical Resonator Modelling
- Thermal motion in the resonator is caused by the dissipation of elastic energy through numerous different mechanisms such as Lattice defects in the bulk of the material, damage on the surface of the resonator, bending due to spontaneous temperature fluctuations, air resistance, and acoustic coupling to the mounting equipment.
- Using models for these dissipation mechanisms, either found in literature or created in a finite element analysis software, we can predict the thermal noise of a given resonator and then optimize the geometry to lower this noise.
