Detection of fluorescence in situ hybridization on human metaphase chromosomes by near-field scanning optical microscopy [PDF]

, 1995
Fluorescence in situ hybridization signals o­n human metaphase chromosomes are detected by a near-field scanning optical microscope. This makes it possible to localize and identify several fluorescently labeled genomic DNA fragments o­n a single ...

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.

Narrow line width operation of a 980 nm gain guided tapered diode laser bar [PDF]

, 2011
We demonstrate two different schemes for the spectral narrowing of a 12 emitter 980 nm gain guided tapered diode laser bar. In the first scheme, a reflective grating has been used in a Littman Metcalf configuration and the wavelength of the laser ...

A single atom detector integrated on an atom chip: fabrication, characterization and application

, 2010
We describe a robust and reliable fluorescence detector for single atoms that is fully integrated into an atom chip. The detector allows spectrally and spatially selective detection of atoms, reaching a single atom detection efficiency of 66%.

Insertion loss and misalignment tolerance in multimode tapered waveguide bends [PDF]

, 2008
Experimental measurements of laterally tapered multimode waveguide bends fabricated photolithographically on FR4 printed circuit board establish that the product of the mean insertion loss (in linear units) and the mean source misalignment tolerance is a

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.

Single and dual fiber nano-tip optical tweezers: trapping and analysis

, 2013
An original optical tweezers using one or two chemically etched fiber nano-tips is developed. We demonstrate optical trapping of 1 micrometer polystyrene spheres at optical powers down to 2 mW.

Phase-locking of two self-seeded tapered amplifier lasers

, 2010
We report on the phase-locking of two diode lasers based on self-seeded tapered amplifiers. In these lasers, a reduction of linewidth is achieved using narrow-band high-transmission interference filters for frequency selection.

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.
