This thesis describes the design, fabrication, and characterization of 3D superconducting microwave cavities for two applications. It first describes a cryogenically compatible microwave filter that is able to tune its resonant frequency by an unprecedented 5 GHz via deformation caused by a a...

Cavity optomechanical devices are interesting systems for probing quantum mechanical behaviour of mesoscopic objects. A basic requirement for these types of experiments is preparation of the mechanical resonator in, or at least very close to, its ground state. Although active laser cooling...

When a photon experiences a change in momentum of any form, be it being absorbed or reflected from a surface, the photon will exert a force upon that material. This force is called the radiation pressure force. One way that we can harness this radiation pressure force is to couple optical and...

Coupling optical cavities to freely moving mechanical devices results in optomechanical systems. Enabled by advancing fabrication techniques, optomechanical systems are now easily fabricated using silicon-on-insulator chips at the micro- and nanoscale. These nano-optomechanical systems (NOMS)...
