Fluorine's effect on fiber optical losses induced by drawing

A. A. Abramov М. М. Бубнов Evgenii M Dianov S. L. Semjonov A. G. Shchebunjaev

Fiber optical losses approaching the ultimately low level are determined mainly by drawing conditions, in particular, by the three interconnected parameters of temperature, speed, and tension, and they also depend on the glass composition. For silica-germanium fibers it was found that germanium-induced losses (UV absorption and Rayleigh scattering) grow with higher temperatures and with lower drawing tensions.12 Yet, for fibers with a pure silica core and a fluorine-doped reflecting cladding the dependence was quite the opposite; namely, Rayleigh scattering grew with increasing drawing tension.3 We have investigated the influence of drawing conditions on the optical losses of silica-germanium fibers, the cores of which are additionally doped by fluorine, and we have shown the possibility of making the losses much less dependent on the drawing temperature and of reducing them to some extent, particularly for the fibers with the higher content of germanium.

Rotation sensors based on single-mode fibers with low and high birefringence

Optical Fiber Sensors (1985)

E. M. Dianov A. Ya. Karasik V. A. Kozlov A M Prokhorov A. K. Senatorov

Rotation sensors based on monomode fibers with low and high birefringence have been studied. A sensitivity of 0.007°√h has been achieved in a device with a (λ = 840-nm) laser diode and 1-km low-birefringence fiber. Long-term stability was ~1°/h.

Development and study of Bragg fibres with a large mode field and low optical losses

Quantum Electronics (2006)

Mikhail E. Likhachev S. L. Semjonov М. М. Бубнов Evgenii M Dianov V. F. Khopin

A silica Bragg fibre with optical losses lower than 10 dB km-1 is fabricated for the first time. The Bragg fibre manufactured by the MCVD method is intended for operation at a wavelength of 1.06 μm and has the mode-spot diameter 18.5 μm (the mode-spot area is 270 μm2). The fibre is considerably less sensitive to bending than step-index fibres and microstructure fibres with the same mode-spot size. The possibility of fabricating a Bragg fibre with the record mode-spot area (530 μm2 at the operating wavelength of 855 nm) for all-silica fibres is demonstrated.

Influence of fluorine doping on drawing-induced fibre losses

Electronics Letters (1993)

A. A. Abramov М. М. Бубнов Evgenii M Dianov L.A. Kol'Chenko S. L. Semjonov

Reduction of drawing-induced losses in silica-germanium singlemode fibres with higher germanium content additionally doped by fluorine has been observed. The core doping by fluorine results in a lower loss and in the weakening of the optical loss dependence of the drawing temperature.

Low-loss, high-aperture germanium–fluorine-codoped single-mode fibers

A. A. Abramov М. М. Бубнов Eugeni M. Dianov К.М. Голант R.R. Khrapko

High-aperture single-mode fibers with GeO2 concentrations of 10–30 mol. % have many applications; for example, they are used as dispersion-compensating fibers and as active fibers for signal amplification and they are a very attractive medium for various efficient nonlinear effects. However, to make best use of the advantages of highly doped fibers, the higher optical losses of such fibers should be minimized to improve their performance. In spite of several investigations, a satisfactory loss level in high-aperture fibers has not been reached to date and the mechanisms responsible for their excess losses are not yet clear.1–4

Bismuth-doped fibre amplifier operating between 1600 and 1800 nm

Quantum Electronics (2015)

Sergei Firstov Sergey Alyshev Konstantin Riumkin V. F. Khopin Mikhail Melkumov

We report the first bismuth-doped fibre amplifier operating between 1600 and 1800 nm, which utilises bidirectional pumping (co-propagating and counter-propagating pump beams) by laser diodes at a wavelength of 1550 nm. The largest gain coefficient of the amplifier is 23 dB, at a wavelength of 1710 nm. It has a noise figure of 7 dB, 3-dB gain bandwidth of 40 nm and gain efficiency of 0.1 dB mW-1.

Circular core polarization-maintaining optical fibers with elliptical stress-induced cladding

Journal of Lightwave Technology (1992)

Evgenii M Dianov A.B. Grudinin A. N. Gurjanov D. D. Gusovsky Z.E. Harutjunian

The reproducible technology for producing high-birefringence fibers with stress-induced elliptical cladding and circular core is described. The authors have obtained fibers that have a birefringence of about (1-3) 10/sup -4/, a mode coupling parameter of about (2-7) 10/sup -5/ m/sup -1/, and loss of less than 0.5 dB/km at 1.6 mu m. The authors have found effects restricting the capability of test fibers to maintain the state of linear polarization.< >
