Microstructured polymer fiber laser

Optics Letters, 2004
A microstructured polymer optical fiber doped with Rhodamine 6G dye was fabricated and demonstrated as an optical amplifier and a fiber laser. As an amplifier, the fiber achieved a gain in excess of 30 dB. As a pulsed fiber laser, the fiber exhibited a threshold of 20 microJ, a slope efficiency of 18%, and a lifetime as high as 130,000 shots at 10 Hz ...

Microstructured Optical Fiber Sensors

2007 9th International Conference on Transparent Optical Networks, 2007
Microstructured optical fiber (MOF) sensors are nowadays utilized or proposed for the measurement of a large variety of physical and chemical parameters, e.g. in environmental and biological applications because of their efficiency and versatility. This paper, at first, gives a short review of MOF sensors reported in literature. An evanescent field MOF

Microstructured and multicore fibers and fiber lasers

2006 Optical Fiber Communication Conference and the National Fiber Optic Engineers Conference, 2006
Microstructured and multi-core fiber lasers were fabricated that have produced more than 1.3 W/cm at 1.5 /spl mu/m. Near 2 W single frequency, single-transverse-mode output was demonstrated.

Comment on “Microstructured polymer fiber laser”

Optics Letters, 2005
We comment on the recent Letter by Argyros et al. [Opt. Lett. 29, 1882 (2004)] in which a microstructured polymer fiber doped with the dye Rhodamine 6G was discussed as a possible fiber laser source. We suggest that the lasing action at 632 nm was due to stimulated Raman scattering in the poly(methyl methacrylate) host material.

Prospective for biodegradable microstructured optical fibers

Optics Letters, 2006
We report fabrication of a novel microstructured optical fiber made of biodegradable and water soluble materials that features approximately 1 dB/cm transmission loss. Two cellulose butyrate tubes separated with hydroxypropyl cellulose powder were codrawn into a porous double-core fiber offering integration of optical, microfluidic, and potentially ...

Microstructured polarizing fiber

SPIE Proceedings, 2005
Introduction of metal elements into the optical fiber's structure creates new possibilities of waveguides' parameters' modification especially permit to obtain polarizing fibers. A known solution is introducing of molten metal into a hole situated along a single-mode fibre's core.

Plasmonic microstructured optical fibers

2015 17th International Conference on Transparent Optical Networks (ICTON), 2015
Placing large aspect-ratio nanowires made from metals into fibers leads to new application areas of optical fibers. Using our pressure-assisted melt-filling approach various hybrid fibers have been fabricated by filling the air holes of photonic crystal fibers with materials such as noble metals, semiconductors, fluids or low-melting compound glasses ...

The microstructure of stabilized fibers

Journal of Applied Polymer Science, 1988
AbstractThe morphology and microstructure of a stabilized fiber, nonburning fiber, has been investigated under optical and electron microscopes, and a model for the structure of the stabilized fiber is presented. Skin‐core morphology was found in the cross section of the stabilized fiber.

Microstructured fiber lasers

2005 IEEE LEOS Annual Meeting Conference Proceedings, 2005
Summary form only given. Microstructured fibers and fiber lasers are providing new approaches for achieving single transverse mode guiding in large core fibers. We have successfully fabricated microstructured fibers from phosphate glass that allows the same high doping levels as in our step index fibers.

Microstructured and Nanostructured Fibers

Integrated Photonics Research and Applications/Nanophotonics, 2006
The optical fiber drawing process makes it straightforward to incorporate two-dimensionally structured materials into optical fibers. We use structured materials to demonstrate several new waveguide designs which illustrate the potential for improved performance.
