Microoptical Realization of Arrays of Selectively Addressable Dipole Traps: A Scalable Configuration for Quantum Computation with Atomic Qubits [PDF]
Phys. Rev. Lett. vol. 89, ID 097903, 2002, 2001 We experimentally demonstrate novel structures for the realisation of registers of atomic qubits: We trap neutral atoms in one and two-dimensional arrays of far-detuned dipole traps obtained by focusing a red-detuned laser beam with a microfabricated array of microlenses.

Microoptics for efficient redirection of sunlight [PDF]
Applied Optics, 2012 Ray-tracing calculations are employed to identify basic design rules for the configuration of microstructured daylighting systems. The results show the advantage of combinations of lenslike geometries in comparison to conventional microprism arrays regarding the overall light redirection efficiency as well as the producibility and cost efficiency ...

High-efficiency ultraviolet inscription of Bragg gratings in microfibers
IEEE Photonics Journal, 2012 In this paper, we demonstrate high-efficiency inscription of Bragg gratings in microfiber. Strong Bragg gratings are easily inscribed using a 193-nm excimer laser and phase mask in microfiber drawn from the 62.5/125- μm standard multimode fiber ...

Ion-Exchanged Waveguides in Glass Doped with PbS Quantum Dots [PDF]
, 2004 The lowest-loss (≤1 dB/cm) ion-exchanged waveguides in glass doped with PbS quantum dots are presented. Near-field mode profile and refractive index profile using the refracted near-field technique were measured for these waveguides.

Fast transport, atom sample splitting, and single-atom qubit supply in two-dimensional arrays of optical microtraps [PDF]
New J. Phys. vol. 14, 123034 (2012), 2013 Two-dimensional arrays of optical micro-traps created by microoptical elements present a versatile and scalable architecture for neutral atom quantum information processing, quantum simulation, and the manipulation of ultra-cold quantum gases. In this article, we demonstrate advanced capabilities of this approach by introducing novel techniques and ...
