Polymicro Technologies (Lisle, IL) has successfully developed a broad spectrum optical fiber with a low -OH pure silica core that demonstrates significantly reduced content of UV defects and other UV absorption centers. Polymicro’s proprietary FBPI fiber leverages the benefits and mitigates the limitations of standard optical fibers. Featuring improved transmission properties over a much wider spectral range, the silica-based, broadband FBPI fiber is available in a range of densities and can be produced in core diameters from 50-600 μm.
In the near-infrared (NIR) wavelength region to beyond 2100 nm, Polymicro FBPI fiber attenuation is equivalent to standard NIR fibers having a low -OH silica core and F-doped cladding. Comparable to solarization properties of standard UV optimized high -OH fibers with high radiation resistance, FBPI fiber features ultra-violet (UV) transmission down to 200 nm.
