A vitreous As2S3 has been produced and characterized with the impurity content of ОН-groups 0.1-0.3 ppb wt, CO2 ~ 1 ppb mole, SH-groups - 0.5-1 ppm mole, scattering centers with the diameter of ≤100 nm - <104 cm-3, and transition metals - ≤0.5 ppm wt. The optical fibers made from this glass have record low optical losses of 12 ± 2 dB/km at 3.0 μm and 14 ± 2 dB/km at 4.8 μm, the average bending strength of 0.52 GPa, and the numerical aperture of 0.21 at 1.55 μm.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
