Pursuing a Ph.D. is not a simple endeavor, and its pursuit begins long before a student begins their journey in graduate school. To do proper justice to everyone in my life who contributed to my efforts would not be possible in the limited scope of this document, but I will attempt to acknowledge the key individuals who got me here, helped along the way in my scientific endeavors, and who helped me maintain the tenuous grip on sanity inherent to graduate studies.

Using a fast detector to observe the light deflected by silica mi- crospheres trapped in an optical tweezer, we obtain positional information from which instantaneous velocities are calcu- lated and fit to the Maxwell-Boltzmann distribution to extract mass. We plan to use this technology to characterize the onset of heterogeneous ice nucleation.

We designed and constructed an optical tweezing apparatus that enabled precision control of dielectric microbeads using a He-Ne laser and an inverted microscope. Its piconewton force capabilities were demonstrated.

A profound understanding of the underlying physics has inspired the emergence of a new frontier of materials and devices in the past few decades. is thesis explores the concepts and approaches for manipulating light at the wavelength-scale in a variety of topics, including anti-reective coatings, on- chip silicon photonics, optical microcavities and nanolasers, microwave particle accelerators, and optical nonlinearities. In Chapter , an optimal tapered prole that maximizes light transmission be- tween two media with different refractive indices is derived from analytical theory and numerical modeling. A broadband wide-angle anti-reective coating at the air/silicon interface is designed for the application of photovoltaics.
