Erbium/Ytterbium Doped Fibers The Optimized Balance Erbium/Ytterbium Co-doped Fibers for 1.5 µm Eyesafe Operation As applications requiring 1.5 μm operation continue to increase, the need for high performance fibers capable of delivering high output power and improved efficiency becomes critical. Nufern has developed a family of highly efficient Erbium/Ytterbium Doped Double Clad Fibers (EYDF). These fibers are optimized to achieve record efficiencies in the 1.5 μm wavelength range while suppressing parasitic phenomenon such as 1 μm Amplified Spontaneous Emission (ASE). Nufern’s approach is to design and offer the highest performance fibers optimized for a range of applications. Available in a wide range of core sizes including true SM designs, as well as LMA and MM options, EYDF’s are ideal for applications ranging from LIDAR to amplifiers for CATV. By balancing the trade- offs between efficiency, power threshold and 1 μm ASE light generation, Nufern offers the highest performance Erbium/Ytterbium doped fibers available.
