Non-Circular Optical Fibers perform high power delivery.

Press Release Summary:




Square and rectangular optical fibers utilizing Direct Nanoparticle Deposition (DND) technology are available in various combinations, such as rectangular core with round cladding or rectangular core with rectangular cladding. Square or rectangular geometries facilitate matching fibers to optical sources, enhance beam control and propagation, and allow for routing of fibers in unique footprints. Applications range from illumination and signs to ordinance detonation.

Liekki Introduces Non-Circular Optical Fibers for High Power Delivery



LOHJA, September 8, 2006 - Liekki, the leading supplier of highly doped optical fibers, has developed the capability to provide non-circular optical fibers for applications requiring high power delivery.

Liekki expands its broad, optical fiber line with the availability of square and rectangular optical fibers. Different combinations, for example rectangular core - round cladding or rectangular core - rectangular cladding are available. The fibers offered today are passive but they will be available as active fibers with ytterbium or erbium doping in the future. "We have been approached by several clients looking for a different geometric solution for high power delivery. Conventional fiber processes are limited by their deposition and glass works to circular optical fibers. Liekki's Direct Nanoparticle Deposition (DND) technology and a unique glass works process overcome these conventional barriers to provide non-circular shapes." says Mr. Mikko Söderlund, Product Manager of Liekki's fiber products.

"Square or rectangular geometries can be beneficial for improved matching to optical sources, improved beam control and propagation and for routing of fibers in unique footprints. It appears that the applications for these fibers are quite broad, ranging from illumination and signs to ordinance detonation", continues Mr. Söderlund.

About Liekki Corporation
Liekki designs, manufactures and markets specialty optical fibers and fiber subassemblies (optical engines) for fiber amplifiers and lasers using its unique and proprietary Direct Nanoparticle Deposition (DND) technology. DND makes it possible to produce state-of-the-art highly doped fibers that minimize required fiber length, have large core-to-clad ratios, and exhibit low photodarkening, flat refractive index profile, high efficiency and reduced nonlinear effects. Liekki fibers also have very good usability in terms of splicing properties, temperature and bending characteristics. Liekki products are used in applications such as high power fiber lasers for industrial manufacturing, military and aerospace, medical applications, telecom amplifiers and ASE light sources.

Direct Nanoparticle Deposition (DND) is a new, innovative nanoparticle process invented, developed and commercialized by Liekki, for a wide range of industrial applications. Liekki has licensed DND to industrial customers for non-optical applications and will continue to do so.

Liekki is headquartered in Lohja, Finland. Liekki products are available globally through Thorlabs (www.thorlabs.com). Liekki direct sales serves North America, Europe and Asia, supported by our representatives FT Okura (Japan), IKG Corporation (Japan), Apollo Electronics Co. Ltd. (China) and Connet Fiber Optics Company Ltd. (China). For further information, please visit our website at www.liekki.com.
