Article: Switching of Light with Light Using Cold Atoms Inside a Hollow Optical Fiber
[show abstract] [hide abstract]
ABSTRACT: eap/ We demonstrate a fiber-optical switch that operates with a few hundred pho-tons per switching pulse. The light-light interaction is mediated by laser-cooled atoms. The required strong interaction between atoms and light is achieved by simultaneously confining photons and atoms inside the microscopic hollow core of a single-mode photonic-crystal fiber.; -
Article: Laser-cooled atoms inside a hollow-core photonic-crystal fiber
[show abstract] [hide abstract]
ABSTRACT: We describe the loading of laser-cooled rubidium atoms into a single-mode hollow-core photonic-crystal fiber. Inside the fiber, the atoms are confined by a far-detuned optical trap and probed by a weak resonant beam. We describe different loading methods and compare their trade-offs in terms of implementation complexity and atom-loading efficiency. The most efficient procedure results in loading of ~30,000 rubidium atoms, which creates a medium with optical depth ~180 inside the fiber. Compared to our earlier study this represents a six-fold increase in maximum achieved optical depth in this system.04/2011; -
Article: Efficient all-optical switching using slow light within a hollow fiber.
[show abstract] [hide abstract]
ABSTRACT: We demonstrate a fiber-optical switch that is activated at tiny energies corresponding to a few hundred optical photons per pulse. This is achieved by simultaneously confining both photons and a small laser-cooled ensemble of atoms inside the microscopic hollow core of a single-mode photonic-crystal fiber and using quantum optical techniques for generating slow light propagation and large nonlinear interaction between light beams.Physical Review Letters 06/2009; 102(20):203902. · 7.37 Impact Factor
