Stable Multiwavelength Erbium-Doped Random Fiber Laser [PDF]

IEEE Journal of Selected Topics in Quantum Electronics, 2018
A stable multiwavelength erbium-doped fiber laser (EDFL) based on random distributed feedback (RDFB) is presented. The random EDFL consists of a half-opened linear cavity in which a mirror forms one end, while the other end is connected to RDFB of a 25-km-long single mode fiber.

Inhomogeneous Gain Saturation in EDF: Experiment and Modeling [PDF]

, 2011
Erbium-Doped Fiber Amplifiers can present holes in spectral gain in Wavelength Division Multiplexing operation. The origin of this inhomogeneous saturation behavior is still a subject of controversy.

Wideband and flat gain series erbium doped fiber amplifier using hybrid active fiber with backward pumping distribution technique

Results in Physics, 2019
A modern wideband and flat gain erbium-doped fiber amplifier (EDFA) is suggested and accomplished, by employing a recently fabricated hafnia-bismuth-erbium doped fiber (HB-EDF) and zirconia-erbium doped fiber (Zr-EDF) as a hybrid active fiber.
