Article comprising a micro-structured optical fiber, and method of making such fiber
TL;DR: In this paper, non-periodic microstructured optical fibers that guide radiation by index guiding are discussed. And a method of making micro-structured fiber is also disclosed, which potentially has many uses, e.g., as dispersion compensating fiber with or without dispersion slope compensation.
Journal ArticleDOI
Optically driven deposition of single-walled carbon-nanotube saturable absorbers on optical fiber end-faces
TL;DR: Single-walled carbon nanotubes have a fast saturable absorption over a broad wavelength range, and the demonstrated technique is an extremely simple and inexpensive method for making fiber-integrated, saturable absorbers for passive modelocking of fiber lasers.
Journal ArticleDOI
Rayleigh scattering limitations in distributed Raman pre-amplifiers

TL;DR: In this paper, the properties and fiber dependence of distributed Raman pre-amplifiers and the effects of Rayleigh backscattering, which limits the sensitivity improvements that can be realized, are discussed.
Patent
Tapered fiber bundles for coupling light into and out of cladding-pumped fiber devices
TL;DR: In this paper, light is coupled from a plurality of semiconductor emitters to a cladding-pumped fiber via tapered fiber bundles fusion splicing to the cladding pumped fiber.
Patent
Optical fiber configuration for dissipating stray light
TL;DR: In this paper, an optical transmission fiber is formed to include a relatively low-index, relatively thin outer cladding layer disposed underneath the protective polymer outer coating, which allows for the stray light to leak into the outer coating in a controlled, gradual manner so as to minimize heating of the coating associated with the presence of stray light.
