Transmission loss characteristics of fluoride glass single-mode fibre
暂无分享,去创建一个
The transmission loss spectrum of a fluoride glass single-mode fibre as obtained with a new preform fabrication technique is shown. It is clearly confirmed on the loss spectrum that the obtained fibre is a single-mode waveguide in the minimum loss wavelength range (2–4 μm). The minimum loss of this fibre is 8.5 dB/km at 2.2 μm and the OH excess loss is 15dB/km at 2.85 μm. This fabrication technique is effective in eliminating OH contamination.
