Generation of tunable q-switched erbium-doped fiber laser based on graphite flakes saturable absorber [PDF]

open access: yes, 2020
Pulsed fiber laser has tremendous application in laser processing and laser sensor. The key element to produce a passively Q-switched fiber laser is by using a saturable absorber (SA).

Five Orders of Cascaded Raman Fibre Laser Oscillation From 1550 nm to Mid‐IR at 2334 nm Wavelength

open access: yesElectronics Letters, Volume 61, Issue 1, January/December 2025.
We experimentally demonstrate five orders of cascaded Raman oscillations (Raman lasers) in a fibre, starting from ∼1550 nm until 2334 nm. ABSTRACT We demonstrate a cascaded Raman fibre laser (RFL) oscillation up to the fifth order Stokes wave, from ∼1550 nm to mid‐IR at 2334 nm, with silica fibres.

Erbium-Doped Fiber Laser With a Microfiber Coupled to Silica Microsphere

open access: yesIEEE Photonics Journal, 2012
A compact erbium-doped fiber laser (EDFL) is demonstrated using a piece of 1.5-m-long erbium-doped fiber (EDF) with a microfiber coupled to a silica microsphere at the output end.

Opportunities, challenges and requirements for introducing space division multiplexing in fibre optical networks

open access: yesIET Optoelectronics, Volume 19, Issue 1, January/December 2025.
The authors discuss opportunities, challenges and requirements for successful commercialisation of space division multiplexing (SDM) in optical networks. The authors consider recent developments in SDM technology and focus on the importance of different geometrical parameters when designing multi‐core fibres and on the design choices for shared SDM ...

Intrinsically stable light source at telecom wavelengths

open access: yes, 2013
We present a highly stable light source at telecom wavelengths, based on a short erbium doped fiber. The high stability arises from the high inversion of the Er3+ion population.

Influence of saturable absorbers on fiber ring laser sensors [PDF]

open access: yes, 2017
In this work, a fiber ring laser sensor has been employed to analyze the influence of passive Er-doped fiber acting as saturable absorber. Lasing modes of fiber ring lasers can be reduced by properly locating a saturable absorber that narrows the ...

Narrow bandwidth Q-switched Erbium-doped fiber laser based on dynamic saturable absorption filtering effect [PDF]

open access: yes, 2020
We proposed a narrow spectral bandwidth Erbium-doped fiber (EDF) laser Q-switched by a homemade saturable dynamic induced grating (SDIG) which is introduced via reforming the structure of a fiber saturable absorbers FSA with a piece of EDF and a fiber ...

Amplification technology for spatial division multiplexing signals transmitted using multicore fibres

open access: yesIET Optoelectronics, Volume 18, Issue 6, Page 179-187, December 2024.
Multicore (MC‐) erbium‐doped fibre amplifier (EDFA) architecture is classified from the viewpoint of the number of erbium‐doped fibre (EDF) cores and its pumping method. In particular, the advantages of cladding pumped MC‐EDFA are shown. Abstract Amplification technologies needed for spatial division multiplexing (SDM) signal transmission have been ...

Observation of polarization domain wall solitons in weakly birefringent cavity fiber lasers

open access: yes, 2009
We report on the experimental observation of two types of phase-locked vector soliton in weakly birefringent cavity erbium-doped fiber lasers. While a phase-locked dark-dark vector soliton was only observed in fiber lasers of positive dispersion, a phase-

Evaluation of an Erbium-Doped Fiber Ring Laser as an Edge Filtering Device for Fiber Bragg Grating Sensor Interrogation

open access: yesPhotonics
An easy-to-implement and cost-effective Fiber Bragg Grating (FBG) sensor interrogation technique based on a ring Erbium-Doped Fiber Laser (EDFL) topology is proposed and experimentally assessed.
