Single frequency erbium doped fiber laser with a highly doped erbium-doped fiber

, 2010
A single frequency Erbium-doped fiber laser (EDFL) operating at 1552.5 nm has been demonstrated by using a 2 m long of newly developed Zirconia-based Erbium-doped fiber (Zr-EDF) as a gain medium. The Zr-EDF is fabricated by combining Zr and Al to achieve

Few-Mode Erbium-Doped Fiber with Three-Layer Center-Recessed Doping for Gain Equalization

Sensors
We propose a design method for few-mode erbium-doped fiber (FM-EDF) incorporating stratified doping. In the simulation design, the FM-EDF effectively reduces the differential mode gain (DMG) through the utilization of stratified doping.
