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

Comparative study of the effective single mode operational bandwidth in sub-wavelength optical wires and conventional single-mode fibers [PDF]
We present the first experimental comparison of effective single mode operation bandwidth in sub-wavelength optical wires (SOWs) and conventional single-mode fibers (SMFs).

High-Speed Micro-Grooving of Metal by Angled Irradiation of Single-Mode CW Fiber Laser
Laser micro-grooving has excellent potential to improve the surface properties of metals. In this study, high-speed micro-grooving of the surfaces of mild steel SS400 and aluminum alloy A1050 was investigated using a single-mode continuous-wave fiber ...

Large Mode Area Single Mode Fiber with a Twisted Polygon-Shaped Core
We present numerical studies on twisted polygon-shaped core fibers for achieving single mode operation with a large mode area propagation in this paper. These large mode area fibers can achieve single mode operation due to twisting-induced high losses to

Entanglement induced by a single-mode heat environment [PDF]
A thermal field, which frequently appears in problems of decoherence, provides us with minimal information about the field. We study the interaction of the thermal field and a quantum system composed of two qubits and find that such a chaotic field with ...

Sensing properties of graphene-oxide-functionalized single-mode–no-core–single-mode fiber structure
A series of single-mode–no-core–single-mode (SNS) optical fiber sensing structures with different thicknesses of graphene oxide (GO) coating were fabricated and tested with glycerin and magnetic fluid solutions.

Wide field interferometric imaging with single-mode fibers [PDF]
Classical single-mode fiber interferometers, using one fiber per aperture, have very limited imaging capabilities and small field of view. Observations of extended sources (resolved by one aperture) cannot be fully corrected for wavefront aberrations ...
