In the last three or so decades, optical scientists have begun to capitalize in earnest on the advances in nanofabrication that is owed to the explosive rise of miniaturized semiconductor electronics. The resulting field, nanophotonics, has opened a vast design space for applied researchers and required revisiting some of the oldest problems and assumptions of optical physics. Polarization, meaning, in the context of light, the direction of oscillation of the electromagnetic field in space, is a particularly malleable property of light that can be used to shape and direct wave fronts, to measure and control light-matter interactions, and to encode information. It remains an underexplored and underutilized feature of nature, though the new methods of nanophotonics can harness its potential to a much greater extent than any previous optical technology platform. This thesis explores some aspects of the role light's polarization plays at the interface of optics and nanotechnology. In particular, it will touch upon the way polarization may be used to control the generation of optical nearfields, how the polarization structure of evanescent waves leads to unusual optical forces, and how nanoscale polarization-transformations enable a new class of polarization-sensitive optical elements. It will also show how nanophotonics may address the problem of measuring polarization based on a new polarimeter architecture. / Engineering and Applied Sciences - Applied Physics
