Detecting Neutral Atoms on an Atom Chip [PDF]

, 2006
Detecting single atoms (qubits) is a key requirement for implementing quantum information processing on an atom chip. The detector should ideally be integrated on the chip.

Single-Mode Fiber Microlens with Controllable Spot Size [PDF]

, 1991
A novel method for fabricating microlenses on tapered single-mode fibers is shown to be able to control the lens spot size. The fiber cladding is first symmetrically tapered by etching it with an evaporating ammonium bifluoride solution.

Astronomical Applications of Multi-Core Fiber Technology [PDF]

, 2020
Optical fibers have altered astronomical instrument design by allowing for a complex, often large instrument to be mounted in a remote and stable location with respect to the telescope.

Butterfly Optics Exceed the Theoretical Limits of Conventional Apposition Eyes [PDF]

, 1987
Optical experiments on butterfly compound eyes show that they have angular sensitivities narrower than expected from conventional apposition eyes. This superior performance is explained by a theoretical model where the cone stalk is considered as a ...

Low-temperature tapered-fiber probing of diamond NV ensembles coupled to GaP microcavities [PDF]

, 2011
In this work we present a platform for testing the device performance of a cavity-emitter system, using an ensemble of emitters and a tapered optical fiber.

Strong extinction of a far-field laser beam by a single quantum dot [PDF]

, 2007
Through the utilization of index-matched GaAs immersion lens techniques we demonstrate a record extinction (12%) of a far-field focused laser by a single InAs/GaAs quantum dot.

Localized fluidization in granular materials: Theoretical and numerical study

, 2016
We present analytical and numerical results on localized fluidization within a granular layer subjected to a local injection of fluid. As the injection rate increases the three different regimes previously reported in the literature are recovered ...
