FWM-based multi-wavelength erbium-doped fiber laser using Bi-EDF
Laser Physics, 2010 We experimentally demonstrate a simple structure but efficient multi-wavelength erbium-doped fiber laser (EDFL) using a 49 cm Bismuth-based erbium-doped fiber (Bi-EDF) as gain medium. The Bi-EDF provides erbium amplification and FWM effect in the cavity to generate a stable multi-wavelength comb operating in C-band region.

Two-stage S-band erbium-doped fiber amplifier using a depressed-cladding fiber
Microwave and Optical Technology Letters, 2005 A two-stage short-wavelength-band erbium-doped fiber amplifier (S-band EDFA) is demonstrated using a depressed-cladding erbium-doped fiber (EDF). The EDF has a fundamental-mode cutoff wavelength of about 1525 nm in order to suppress amplified spontaneous

Abstract We experimentally demonstrate an all-fiber erbium-doped fiber ring laser based on a Sagnac interferometer with a low modal crosstalk mode multiplexer/demultiplexer (MUX/DEMUX). Three linearly polarized (LP) modes are generated by mode MUX/DEMUX, which consists of cascaded mode-selective couplers.

This paper presents the operation of full duplex bi-directional Er doped fiber amplifier (B-EDFA) developed on a common erbium doped fiber. The approach of employing a single EDF is in contrast to the conventional B-EDFA which uses two separate EDF system.

Enhanced Erbium–Zirconia–Yttria–Aluminum Co-Doped Fiber Amplifier [PDF]
IEEE Photonics Journal, 2015 An efficient optical amplifier is demonstrated using an improved erbium-zirconia-yttria-aluminum co-doped fiber (Zr-EDF) as the gain medium. With a combination of both Zr and Al, we could achieve a high erbium doping concentration with an absorption loss
