【 摘 要 】

The Verdet constants of PbS-doped silica optical fiber and single mode fiber (SMF-28e) have been investigated based on a magneto-optical effect measurement system at wavelengths between 660 and 1550 nm. The Verdet constant of PbS-doped fiber is 3.17 rad/Tm, 31.5% larger than that of SMF at 660 nm. The PbS-doped silica optical fiber can become a promising material for Faraday rotator.
