The exceptionally large polarizability of highly excited Rydberg atoms-six orders of magnitude higher than ground-state atoms--makes them of great interest in fields such as quantum optics, quantum… (More)
We present time-resolved reflectivity spectra of optically, homogeneously switched photonic crystals. We observe large, ultrafast shifts of stopbands of GaAs/AlAs multilayer structures as well as in… (More)
We report a sensitive evanescent field sensor using air-suspended solid-core fibers. Excellent agreement between measured and calculated mode profiles allows us to measure quantitative broadband… (More)
We present the first room-temperature results on a three-photon excitation of Rydberg states in cesium atoms placed inside a kagomé-style hollow-core photonic crystal fiber.
We present a versatile method for selective mode coupling into higher-order modes of photonic crystal fibers, using holograms electronically generated by a spatial light modulator. The method enables… (More)
A great challenge in microfluidics is the precise control of laser radiation forces acting on single particles or cells, while allowing monitoring of their optical and chemical properties. We show… (More)
Photonic crystal fiber (PCF) has proven very useful for enhancing light-matter interactions, offering interaction lengths much longer than those available using conventional techniques. A… (More)
We discuss two recent applications of hollow-core photonic crystal fibre.
We report the successful transport of spatially entangled qutrits through a photonic crystal fiber. We test entanglement in two 2D subspaces; in one of them we show violation of a Bell inequality.
