On-chip nano-optomechanical whispering gallery resonators
This thesis work focuses on the design, fabrication and measurement of Gallium Arsenide (GaAs) nano-optomechanical disk resonators. These disks are both GHz frequency mechanical resonators, and high Q (> 10) optical whispering gallery mode resonators. By confining optical and mechanical energy on a sub-μm volume, they enable extremely large optomechanical coupling strengths (g0 >1 MHz). We pres...
متن کاملQuantum-limited amplification and parametric instability in the reversed dissipation regime of cavity optomechanics.
Cavity optomechanical phenomena, such as cooling, amplification, or optomechanically induced transparency, emerge due to a strong imbalance in the dissipation rates of the parametrically coupled electromagnetic and mechanical resonators. Here we analyze the reversed dissipation regime where the mechanical energy relaxation rate exceeds the energy decay rate of the electromagnetic cavity. We dem...
متن کاملPhotoelastic coupling in gallium arsenide optomechanical disk resonators.
We analyze the magnitude of the radiation pressure and electrostrictive stresses exerted by light confined inside GaAs semiconductor WGM optomechanical disk resonators, through analytical and numerical means, and find the electrostrictive stress to be of prime importance. We investigate the geometric and photoelastic optomechanical coupling resulting respectively from the deformation of the dis...
متن کاملForce sensitivity of multilayer graphene optomechanical devices
Mechanical resonators based on low-dimensional materials are promising for force and mass sensing experiments. The force sensitivity in these ultra-light resonators is often limited by the imprecision in the measurement of the vibrations, the fluctuations of the mechanical resonant frequency and the heating induced by the measurement. Here, we strongly couple multilayer graphene resonators to s...
متن کاملDamping in a superconducting mechanical resonator
We study a mechanical resonator made of aluminum near the normal-tosuperconducting phase transition. A sharp drop in the rate of mechanical damping is observed below the critical temperature. The experimental results are compared with predictions based on the Bardeen Cooper Schrieffer theory of superconductivity and a fair agreement is obtained.
