SM Erbium/Ytterbium Doped Fiber Fibercore’s SM Erbium/Ytterbium Doped Fiber (DF1500Y) is a Single-Mode (SM) Erbium (Er) and Ytterbium (Yb) doped fiber, providing extremely high levels of pump absorption and emission around the telecoms C and L band windows. The fiber can be used for lower power fiber lasers, pre-amplifiers and Amplified Spontaneous Emission (ASE) light sources. The high absorption is ideal for applications requiring short gain lengths, for example femtosecond mode-locked ring lasers. The mixture of Erbium and Ytterbium extends the 915nm pump absorption band to 980nm with a relatively flat absorption rate until the 980nm peak.
