Twin-core optical fiber with large core ellipticity
Applied Optics, 1991The first (we believe) twin-core optical fiber with large core ellipticity has been fabricated, and its significant polarization dependent coupling properties have been demonstrated.

A novel in-fiber optical switch based on two-core optical fiber
SPIE Proceedings, 2007A novel in-fiber optical switch based on two-core optical fiber is demonstrated. A Mach-Zehnder intereferometer was integrated into a single optical fiber of 125 μm diameter using a novel coupling connection technology. Then embedding the single optical fiber into a universal optical fiber transmission line, the novel in-fiber optical switch is formed.

Triboluminescence of silica core optical fibers
Applied Physics Letters, 1982The triboluminescence spectrum of optical fibers contains two prominent peaks, one at 430 nm and the other at 630 nm. The relative intensities vary with fiber type. The time dependence of the emission is related to the crack rate terminal velocity and to the creation and annihilation of moving cracks.

Magnetic-fluid core optical fiber
Microfluidics and Nanofluidics, 2010We report the first fabrication of magnetic-fluid core optical fiber (MFCOF). Paraffin-based magnetic fluid is selected as the liquid and filled in a hollow core fiber with the core-diameter of 5 μm and the length of 20 cm. The optical properties of MFCOF were investigated by sending light into them.

Two-core optical fibers: experiment
Journal of the Optical Society of America A, 1985Two-core fibers are investigated experimentally. Low-loss birefringent single-mode two-core fibers, consisting of two cores and a pair of stress-inducing parts built in a cladding, were prepared. A power exchange of the order of a few millimeters occurs as a result of the coupling between the two cores.

Viscosity of silica core optical fiber
Journal of Non-Crystalline Solids, 1999Abstract Since we found that Rayleigh scattering of silica core optical fiber can be reduced by heat treatment, we studied the viscosities of the fiber to investigate this phenomenon from the viewpoint of viscous relaxation. To this end, the viscosity of silica core fiber was measured by the bending method in a temperature range of 1050–1200°C.

Advancements in semiconductor core optical fiber
Optical Fiber Technology, 2010Presented here is a review of recent progress in the nascent field of glass-clad semiconductor core optical fibers. Such fibers, generally focused to-date on silicon and germanium cores, define a new class of optical fibers that have the potential to significantly advance the fields of nonlinear fiber optics and infrared power delivery.

Novel Crystalline Core Optical Fibers
Optical Fiber Communication Conference and National Fiber Optic Engineers Conference, 2009This work discusses advances in fabricating glass-clad crystalline core optical fibers. Of greatest significance is that these crystalline core fibers were produced using scalable and commercially accepted optical fiber draw processes.

Elliptical core multimode optical fibers
2012 17th Opto-Electronics and Communications Conference, 2012We propose a new elliptical core polarization maintaining multimode fiber design with low index trench. We analyze fiber properties such as birefringence, modal delay, bandwidth and mode coupling using a finite element method.

Optical Fibers With a Finite Metallic Core
Journal of Lightwave Technology, 2009Optical step index fibers can be produced that include a thin metal wire in the centre of the core. Such fibers are particularly interesting with respect to their guiding properties. With the goal to theoretically analyse their modes, we summarize three analytic solutions for dielectric media containing a thin metallic wire.
