Nonlinear Cavity Optomechanics in Diamond
… that consists of spins, photons, and phonons. Cavity optomechanics provides a platform to increase the interaction time between photons and phonons. By increasing the average number of photons and phonons, the coupling rates will be enhanced, and better control over the system could emerge as a …

Periodic driving and nonreciprocity in cavity optomechanics
Part I of this thesis is concerned with cavity optomechanical systems subject to periodic driving. We develop a Floquet approach to solve time-periodic quantum Langevin equations in the steady state, show that two-time correlation functions of system operators can be expanded in a Fourier series, …

TUNING AND OPTOMECHANICS OF COUPLED PHOTONIC CRYSTAL NANOBEAM CAVITIES
This thesis focuses on mechanical tuning and optomechanics of photonic devices based on coupled photonic crystal nanobeam cavities, with studies including nano fabrication process development, device tuning with NEMS actuators, investigation of optical gradient force and tunable cavity …

Nanophotonic Optomechanical Devices for Torque Magnetometry
… resonators. Over the years, the field of cavity optomechanics has demonstrated ever increasing sensitivity, with measurements limited by the quantum motion of a device possible in state-of-the-art devices. In this thesis, a nanophotonic cavity is integrated into a nanomechanical resonator …

Non-suspended optomechanical cavities
… system used by a quantum communication network. Cavity optomechanics enhances photon-phonon interactions by co-localization of optical fields and mechanical resonances. The implementation of phononic localization in the majority of cavity optomechanical devices relies on creating suspended …

Manufacturing and aerostatic tunability of opto-mechano-fluidic resonator and its application in viscosity sensing
Cavity optomechanics experiments parametrically couple the phonon modes and photon modes in microresonators and various optical systems have been investigated. However, because of the increased acoustic radiative losses during direct liquid immersion of optomechanical devices, almost all published …

Ultrasensitive Force Sensing with Nanospheres in an Optical Standing Wave Trap
… nm, incident on a single hemispherical optical cavity, we have successfully trapped nano-spheres inside the optical standing wave trap. In this thesis we outline the frequency stabilization system, the optical cavity, and experimental progress in overlapping both optical standing wave traps. We …

Optomechanical Spin-Photon Interface in Wide-Bandgap Materials
… between the mechanical resonator and optics. Cavity optomechanical devices overcome this impediment by integrating mechanical resonators with an optical cavity. Device engineering can maximize cooperativity, which describes the probability of coherent interaction between photon and phonon …

Nonlinear dissipative dynamics of optomechanical and laser arrays
In this thesis, we study nonlinear dissipative dynamics of two different systems: (i) synthetic dynamical gauge fields for photons in optomechanical arrays and (ii) laser arrays with a topologically nontrivial structure. The chosen models are relevant to state-of-the-art optomechanical experiments …
