摘要：
The authors investigated the effect of deuteration on reducing OH absorption loss for Na2O-Al2O3-SiO2 (NAS) glass, which is a candidate for use in fabricating ultra-low-loss fibre. A deuterated NAS glass fibre was fabricated using the double crucible method and a loss reduction of 800dB/km was achieved at a wavelength of 1.55 mu m. Further, the authors found that a loss increase above 1.51 mu m in the NAS glass fibre was caused by the absorption of hydrogen-bonded OH groups.
