FIBERCORE: PUTTING CUSTOMERS FIRST

SOUTHAMPTON, UK: 23.01.09: Fibercore Limited, the World's leading developer and manufacturer of specialty optical fibers, and a UK subsidiary of Cisco Systems, Inc has launched the SM300, a single-mode fiber with an undoped silica core, designed specifically for high power medical and biotechnical applications. The fiber will be showcased at Photonics West (24 - 29 January 2009) on Fibercore Limited's booth #6071.

SM300 is suitable for applications that require a single mode and/or high beam quality to be delivered in ultraviolet, blue or green wavelengths (300nm to 560nm) such as Laser Doppler Velocimetry (LDV), Laser Doppler Anenometry (LDA), holography and Two-Photon Spectroscopy.

The new fiber addresses the problem of photo-darkening in conventional fibers when transmitting more than a few milliwatts in the ultraviolet, blue or green portions of the spectrum. SM300 utilises an un-doped silica core with a Fluorinated silica cladding rather than a conventional Germanium-doped silica core. The advantage of this is that with the vast majority of the power travelling in pure silica, the generation of Germania defects that have been so damaging to transmission is no longer an issue. With a cut off below 300nm, the long wavelength portion of the ultra violet spectrum is also accessible.

Furthermore, the numerical aperture is relatively low; typically between 0.1 and 0.11 maximising the model area, minimising the power density and increase the non-linear threshold. This is important in addressing non linear, typically Brillouin, scattering.

Dr Chris Emslie, Managing Director of Fibercore Limited, comments, “SM300 is the first in a planned range of fibers that will include both single mode and polarisation maintaining variants, covering those wave lengths most at risk from photo-darkening between 300 and 532 nm. Its characteristics enable customers to achieve results that would not be possible from fibers currently available on the market. SM300 builds on Fibercore Limited's long-term ethos of delivering high quality specialty fiber for customers' specific needs, supported by enhanced product, application and technical support at every stage of the customers project from the initial birth of an idea through to production roll-out.”
