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

open access: yesResults 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.

All-fiber Mach–Zehnder comb filter based on tapered fibers for wavelength switchable erbium-doped fiber lasers

open access: yesInternational Journal of Optomechatronics, 2020
A wavelength switchable erbium-doped fiber laser was constructed based on an all-fiber Mach–Zehnder interferometer (MZI) comb filter. The MZI consisted of a fiber with two tapers.

Efficient low-threshold lasers based on an erbium-doped holey fiber [PDF]

open access: yes, 2005
We report experimental results on the continuous-wave lasers based on a small core erbium-doped holey fiber. In a simple Fabry-Perot-type cavity with high output coupling, we demonstrate low-threshold (0.55 mW) high slope-efficiency (57.3%) operation ...

Flat-gain wide-band erbium doped fiber amplifier by combining two difference doped fibers [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2015
A new erbium-doped fibre amplifier (EDFA) is demonstrated using a combination of newly developed Erbium Zirconia co-doped fiber (Zr-EDF) and the commercial silica-based Erbium-doped fiber (Si-EDF) as the gain medium.

A Novel Erbium-Doped Fiber Laser Chaotic Circuit Based on Memristor and Its Circuit Implementation

open access: yesIEEE Access, 2021
In this paper, a new chaotic system is proposed by adding a magnetron memristor to an erbium-doped fiber laser circuit, and its dynamical characteristics are analyzed. A special periodic coexistence attractor phenomenon was discovered during the analysis,

Intrinsic multichannel power control in cascaded power-equalizing erbium-doped fiber amplifiers [PDF]

open access: yes, 2000
We numerically investigate the performance of a cascade of four-channel power-equalizing reflective erbium-doped fiber amplifiers (EDFAs). The EDFAs reflect different channels at different points so that different channels interact with partly different ...
