Phosphate-doped transmission fiber with over 40 THz Raman-gain bandwidth
european conference on optical communication(2001)
摘要
We fabricated P-doped silicate fibers, which have two Raman gain peaks at around 13 THz and 40 THz. WDM pumping by semiconductor LDs generates over 40 THz continuous gain bandwidth with two broad gain bands.
