- ItemOpen AccessSynthesis and Thermodynamics of Tapered Optical Nanofibers(2018-03-15) Anderson, Paul; Lvovsky, Alexander I.; Trudel, Simon; Barclay, Paul; Knudsen, David J.; Simon, Ch. H.This thesis pertains to the synthesis and use of tapered nanofibers (TNF) in quantum optics experiments. TNFs are optical fibers which contain a region radially tapering down to a submicron diameter. The key feature of such fibers is that a significant portion of an internally propagating electromagnetic field is just outside the fiber in the form of an evanescent field. TNFs are used to substantially improve light-matter interactions by providing a constant small focus of light along millimeters or centimeters of length. Here we report the successful synthesis of a low-loss TNF of custom geometry both theoretically and experimentally. Additionally, we study the thermodynamics of such fibers, demonstrating the ability to measure their temperature resulting from a coupled laser. Finally, we demonstrate the ability to recover lost transmission, due to atoms adsorbed on the fiber's surface. We conclude with an outlook on future experiments with TNFs.
