Item Ladder-type electromagnetically induced transparency using nanofiber-guided light in a warm atomic vapor(American Physical Society (APS), 2015-10-05) Jones, D.E; Franson, J.D.; Pittman, T.B.We demonstrate ladder-type electromagnetically induced transparency (EIT) using an optical nanofiber suspended in a warm rubidium vapor. The signal and control fields are both guided along the nanofiber, which enables strong nonlinear interactions with the surrounding atoms at relatively low powers. Transit-time broadening is found to be a significant EIT decoherence mechanism in this tightly confined waveguiding geometry. Nonetheless, we observe significant EIT and controlled polarization rotation using control-field powers of only a few microwatts in this relatively robust warm-atom nanofiber system.Item Ultralow-power nonlinear optics using tapered optical fibers in metastable xenon(American Physical Society (APS), 2013-11-06) Pittman, T.B.; Jones, D.E; Franson, J.D.We demonstrate nanowatt-level saturated absorption using a subwavelength diameter tapered optical fiber (TOF) suspended in a gas of metastable xenon atoms. This ultralow-power nonlinearity is enabled by a small optical mode area propagating over a relatively long distance through the Xe gas. The use of inert noble gases in these kinds of TOF experiments may offer practical advantages over the use of reactive alkali-metal vapors, such as rubidium.Item Ultralow-power nonlinear optics using tapered optical fibers in noble gases(OSA Publishing, 2014) Pittman, T.B.; Jones, D.E; Franson, J.D.We demonstrate ultralow-power optical nonlinearities using a sub-wavelength diameter tapered optical fiber in a gas of metastable xenon atoms. The use of inert noble gases offers advantages over reactive alkali vapors such as rubidium.
