Optomechanics and nonlinear mechanics of suspended photonic crystal membranes
The recent demonstration of strong interactions between optical force and mechanical motion of an optomechanical structure has led to the triumphant result of mechanical ground-state cooling, where the quantum nature of a ...
Fourier optics for wavefront engineering and wavelength control of lasers
Since their initial demonstration in 1994, quantum cascade lasers (QCLs) have become prominent sources of mid-infrared radiation. Over the years, a large scientific and engineering effort has led to a dramatic improvement ...
Nonlinear optics in titanium dioxide: from bulk to integrated optical devices
In this thesis, we explore titanium dioxide (TiO2) for ultrafast, on-chip nonlinear optics by studying it in bulk, thin films, and in integrated nonlinear optical devices. TiO2's large nonlinear index of refraction (30 ...
Near-Field Optical Forces: Photonics, Plasmonics and the Casimir Effect
The coupling of macroscopic objects via the optical near-field can generate strong attractive and repulsive forces. Here, I explore the static and dynamic optomechanical interactions that take place in a geometry consisting ...
